i can't think of a reason unless you had a capital loss carryover from 2021. I found turbotax miscalculatd the
AMT S-t and L-t c/o from 2021 to 2022.
otherwise look at form 6251 to see which line the AMT adjustment is posted to.
I did think of one possible reason. you traded Publicly Traded Partnerships and the K-1 sales schedule had adjustment for AMT purposes which would mean your gain/loss for regular tax purposes would be different than that reported for AMT gain/loss
