I know I have AMT credit carryover from 2020, which is showing in my 2020 form 8801 line 26 (Credit carryforward to 2021). However, using turbotax 2021 Home & Biz, when I go to 'Deductions&Credits' -> 'Estimates and Other Taxes Paid' -> 'Credit for AMT paid in Prior Year', I get 'It turns out you don't qualify for this credit'.
I try to go to form 8801 line 19 directly to fill out the amount, but line 19 is not fillable.
P.S. I was able to use my AMT credit last year, when doing my tax return using Turbotax 2020 Home$Biz. I am sure that my AMT credit is not expired yet.
Very much appreciated if anyone can help me!
