Same problem is occurring in 2020 tax returns. In Fixed Asset Manager asset was disposed with $0 gain. It had Special Depreciation of 100%. When the assets were imported to ProSeries, the disposition is shown as an AMT adjustment on Form 6251 line 2k. There should not be any recapture or AMT. After experimenting, if you put a $0 in the Asset Entry Worksheet Depreciation Deduction AMT column (it was blank for that field; the Regular Tax depreciation deduction had $0) it fixed the problem. 

COME ON PROSERIES - THIS WAS A PROBLEM FOR 2019 RETURNS AND YOU DID NOT FIX IT FOR 2020 RETURNS EITHER. I WONDER HOW MANY PREPARERS MAY HAVE MISSED THIS.

WITH THIS ERROR AND AND SOME OTHER PROBLEMS, I AM BEGINNING TO THINK I MAY NEED TO LOOK AT OTHER SOFTWARE BESIDES INTUIT. THE TRUST LEVEL IS DISAPPEARING FAST.
