Why is it asking for AMT when doing a loss carryover for home sale?

[amymillion]

I'm amending a 2020 return to include a loss carryover from 2018 and 2019 but Intuit is saying I need to enter AMT amounts before clearing diagnostics.  AMT is not applicable here.  Tax payer is w-2 employee with 37,000 income and taxes were withheld, she received a refund.  She has a loss carryover of $3000 for a total of $15,000 loss in 2018.

AMT losses may be the same as regular losses, or they may be different.

Either way, the AMT losses have to be entered.

I'm still trying to figure out how you could have a loss on a home sale.  Maybe it wasn't the taxpayer's home, it was a rental?

Hmmm Bob.  Good point, I missed the part about a 'home' that is in the subject line.
