I did in-plan conversion to ROTH 401K incl some post-tax money. Do I include non-taxable post-tax on line 3e form 1116, or subtract it in worksheet?

On 1040, post-tax is in 5a but not 5b. It is reducing my foreign tax credit and I know it is not taxable.

Form 1116, line 3e, is what my original question was really about. I have since looked at past years, and the number that TurboTax enters is always much higher than my total gross income even though I did not do any post tax conversions, so that is not the issue. I posted another post asking how TurboTax is calculating this number and requesting that they add a worksheet showing the calculations.
