No, the form needs to be correct. I just created a whole new return and added the 1099-R and went through every one of the questions asking about IRA's. You input the basis on one screen. Another screen asks for the value at the end of the year, I used zero for that claiming I had rolled it all over. I am having no issue. Here is what I did:

1. Enter the 1099-R
2. Check I converted it to Roth
3. Did you convert all? I said yes
4. Done
5. Disaster, no
6. Nondeductible contributions, yes, enter basis on Dec 31, 2024 I entered $xxx
7. Value on Dec 31, 2025 - I entered zero, as if I had emptied the account
8. Form is perfect.

I can't see what you are doing but customer support can. You may want to give it one more go and then  contact support.

I wonder if you could have a piece of data stuck. A full or corrupted cache can cause problems in TurboTax, sometimes you need to clear your cache (that is, remove these temporary files).

Online version:

1. Delete the form  8606 and 1099-R, see How to Delete
