To further clarify, in 2020 I put zero in the box "Taxable Pension or IRA" and left the box "Taxable Roth IRA Conversion" filled with my conversion amount. This seemed reasonable given the big "OR" between the two boxes. The effect was that TT did not include my conversion amount in my taxable income for Alabama, and I fear I correspondingly significantly underpaid my taxes. For 2021, TT populates both boxes with the conversion amount, even though the big "OR" between the two, and my Alabama tax is correspondingly much higher. Which approach is correct? From what I read, the Roth conversion is taxable by Alabama, so populating both boxes with the conversion amount seems correct, but the form is certainly confusing.
