I had sold several rental houses in 2021, with depreciation recapture and all the other issues that come along with that. So I got an early start on my taxes to give myself time. I waited over a month for that Form 6251 to be ready, and filed shortly after it was available. After reading your post, I wonder if adding in the form late in the game could have caused a bad calculation in TT. It doesn't seem logical, but if we both experienced the same thing, you have to wonder.
