I'm working on my Foreign Tax Credit (Form 1116) via the interview process. After reviewing my FTC carryovers, and then my AMT FTC Carryovers, TurboTax presents a screen that asks me: "Explain how you calculated the amount of foreign tax credit carryover from 2020." And gives me 4 empty lines.
I'm mystified because I have simply accepted the numbers it filled in from my previous return. It seems like my explanation would be: "TurboTax did it." Or According to 2020 Form 1116. Or maybe blank, since I've made no adjustments to TT's numbers. (I didn't carry back anything since I've had plenty of carry-forwards in previous years.)
