Message about changes to Form 3800 not being finished

While doing my Business return for 2023 (S corp) TT gave message that IRS was still working on changes to something to do with Form 3800 but I could continue working on the return. So I finished it all up and am now at the Efile screen.

I have no idea if this change affects my return or not. Should I not file yet? My business had a loss. I want to move on to my personal return and get this all done. But if that will cause the need for amending later, I will wait. When are these new IRS calculations going to be in TT?

Any advice would be appreciated.
