I have clearly mentioned in my original post:

TP made a nondeductible IRA contribution of $ 7,000 in 2024 and converted the same $ 7,000 into a Roth IRA in 2024. IRS balance as of 12/31/2024 is zero.

I have done all the inputs very correctly and even though the Intuit Proseries techs (8 people) have worked on sanitized files, they cannot produce a correct Form 8606. I am so frustrated.

Since there is no amount on line 4 (which is zero), line 4 minus line 4 should be 7000 but the Form 8606 does a wrong math calculation and gives zero on line 5.

All other lines then give wrong data on Form 8606.

This is a very common form, and I'm wondering if anyone in the community has faced this problem with Intuit ProSeries.

I used two other online free programs to check how they prepare the Form 8606, and both of these other free programs prepare a perfectly correct Form 8606.  I am concerned why Intuit Proseries has this glitch in their program, and I am waiting for the answer.
