look in Forms View (Desktop version) and search for the form. Is the tax refund on form 6251 as I suggested?
and then look at Form 8801; it's a lot of math but the intent is to provide a credit due to the situation you describe. if line 18 is positive, there should be a credit; if negative, there is no adjustment
it is very challenging to understand the complexities of Regular taxes and AMT, but unless you want to delve into all the math, it's correct.
