Think I’m running in to the same issue here. At first I was asked to enter Value from 2021 Schedule D for AMT, line 15. I entered the value. I did not owe AMT so I entered the value on line 15 of my regular Schedule D. Now it’s asking me Value from 2021 Form 6251, line 4, alternative minimum taxable income. I do not know what to enter here since I did not file a Form 6251.
