I an very new to DxO Photo Lab. I edited some photos and want to export back to LR with the edits applied, but the edits do not appear to have been exported with the files. I tried exporting as a TIFF and that seemed to work, but TIFF creates a larger file, which I would rather not have. Is there a way to export as DNG with the edits applied?
No. See here:
Why does DxO PhotoLab now export DNG files with only technical corrections? – Help center
That is a feature that is no longer available. You can only export to DNG with DeepPRIME denoising and optical corrections available in the lens profiles for things like Chromatic aberration, Lens distortion, Vignetting, and Lens Sharpness Optimization. A number of users have expressed dissatisfaction that other edits can no longer be applied to DNG in PhotoLab 9.

That is disappointing, DxO mark an “X” on the negative side of switching after the trial ends.
Curious…is there a specific reason you are exporting back to LR?
If it’s something that PL can’t do, understandable! Otherwise there may be some sage advice in these forums to help with your transition!
I am just now exploring PL. I have been a LR user for many years, basically since it started. So I am trialing PL, and am making a list of Pros & Cons of switching to PL. This one issue is on the Con’s list. We will see how the next 30 days goes.
Cool…I am less than a year into the DxO world - I got tired of Adobe’s subscription fees and having Creative Cloud gumming up my system. I tried DT and was mystified by the learning curve (more like a vertical wall).
Admittedly, you’ll find some things that DxO does that can cause some stomach discomfort, but ultimately, you pop a proverbial antacid and then realize it’s not really a problem - just a workflow change. I’ve been incredibly pleased with my switch.
Lots of good people on these forums sharing a lot of good info - and to alleviate any concerns, I’m not a shill working for DxO! Keep the questions coming - there is life after LR!
As you have found out DXO have disabled this functionality, which used to work until recently. It’s unfortunate as I used to recommend people purchase PhotoLab rather than PureRaw as I thought the extra cost was worthwhile for the increased functionality. Do your noise reduction in PhotoLab and your broad tonal edits, and then finish off in LR or whatever. People might realise that in many cases they could do all of their edits in DXO-Photolab. That argument is no longer valid. 
As of the current version (6.3.1), DxO PureRaw still allows exporting back to Lightroom Classic in DNG with PureRaw’s corrections applied. Who knows what the future holds; DxO killed off DNG exports with inadequate warning in the view of many licensees in a PhotoLab update earlier this year, so they may do that with PureRaw, too. Your only defense against this is to keep the earlier version as a downloaded install file you could revert to, in which DNG export still worked, but then you’d lose the update/upgrade path.
PureRaw cannot perform many corrections PhotoLab can apply, but it does apply the optical corrections, all noise reduction models including the newest, and some sharpening and works very well (in two key ways, better*) interacting with Lightroom than Photo Lab. It’s also less expensive. You said you’re a new PhotoLab user. If you’re in a PhotoLab trial or within 30 days of purchase, you can try PureRaw, and if it better fits your workflow, bail out of PhotoLab at no extra cost. DxO does not offer “crossgrade” discounts between PhotoLab and PureRaw; they are separate licenses entirely.
*What’s better in PureRaw than PhotoLab for Lightroom users: PureRaw allows disabling exports to a Lightroom Collections folder and allows better customization of the exported file name, which can save some minor but annoying extra work back in Lightroom. PhotoLab, at least as of version 8, did not allow those options.
Even with the the current editing restrictions in PhotoLab it still allows exporting to DNG with the same DeepPRIME and optical corrections as PureRaw.
