Get your taxes done using TurboTax

if you don't see 8606 in the PDF or in your forms list without doing Open Form etc then it's not going to get filed, something is wrong

 

going back to your entries you said you had done, to clarify - you had basis carryover from 2024 but didn't have a contribution for 2025?

 

in the section under Deductions & Credits / Retirements and Investments / Traditional and Roth IRA Contributions, have you gone through that, and you will get a question

 

Traditional IRAs
Did you have any nondeductible IRA contributions to your traditional IRA from 2024 or prior years?
Nondeductible contributions are tracked on Form 8606 in your prior year returns.
 
which should be yes, then it will ask your basis as of 12/31/24 which should be filled in from the data transferred from your 2024 return.... did you go through this step and what is it showing?
