How did TT calc form 6251 for 2017? Re-figuring my AMT and per 2017 IRS worksheet I shouldn't have paid AMT last year (or this year). Cant follow TT calcs that I owed AMT

If you look at the 6251, it's pretty self-explanatory.  All the adjustments are listed, the tentative AMT is calculated, then the final AMT.  The interview Step-by-step screens also do an excellent job of telling you exactly how the AMT was calculated.  You can call Support to request a 2017 CD/Desktop version of the product, and how to find and open your 2017 return in that version.  You then go to Federal Taxes, Other Tax Situations, AMT to walk back through the interview screens.

Thanks! The issue is that the TT figures don't match what I get when I fill out the IRS 6251 worksheet and the TT calculations for "income exempted from AMT" and "Alternative Minimum Tax" are a black box. In other words, I cannot tie what TT is calculating to the 6251 worksheet (when I fill out the worksheet myself)

***To clarify: I can (now, with the help of the internet) follow the TT calculations on form 6251. What I cannot reconcile is that according to the IRS 2017 1040 instructions "Worksheet To See if You Should Fill in Form 6251—Line 45", I did NOT owe AMT in 2017 and should *not* have filled out a Form 6251. Why then did TT decide Form 6251 was necessary for me (and it resulted in AMT owed)?
