I don't understand your comment since line 11 description on the form is "This is the nontaxable portion of the amount you converted to Roth IRAs". So form 8606 does calculate nontaxable portions, on line 11, 12, 13.
Anyway, we're getting away from the problem I wanted to report. Let me rephrase it, focusing on the numbers calculated by Turbotax in my form.
- line 8 is 1. That's fine.
- line 10 is shown as 0.00000. That's fine.
- line 11, which is line 8 multiplied by line 10, shows 1. That doesn't look correct. 1 multiplied by 0.00000 should be 0.
