Montana does not allow you to claim a fourth quarter federal estimated tax payment made in 2021.
The instructions for Line 4 say "Enter the total amount of federal income taxes paid in 2020." See page 25 of the 2020 Montana Form 2 instructions. You can claim the 2019 fourth quarter federal payment made in 2020.
TurboTax includes a space for that in the Montana section on the screen Federal Income Tax Paid.
