AMT capital loss carry over

[ghappy21]

I have capital losses (from stocks and options) from 2020, to carry into 2021. TT shows those values in Carry Over Worksheet 12a and 13a.

However TT shows zeros in 12b and 13b which are the AMT capital loss entries in the Carry Over Worksheet.

In 2020, I was not exposed to AMT.  For 2021, TT seems to calculate AMT without using the 2020 losses against 2021 gains.  I assume that is not correct.

Should I manually populate 12b and 13b with the same values in 12a and 12b?
