did you use schedule A of 1045 to figure your NOL for 2021. its possible to have a business loss but not have an NOL because of other income. Turbotax as far as I know doesn't compute NOL carryovers so its for you to figure and then enter in the appropriate box
for AMTpurposes use line 4 of 6251 for line 1 of schedule A
you do not reduce 2021 NOL for 2022 net income that's only done when computing if you still have some NOL left over to use in 2023 again using schedule A of form 1045.
