@KLCIt don't use PS but it sounds like it's the way input is (or rather has to be) made, if the number of F.6251, Line 2k, is positive and is the difference that you adjusted with Code B.  That would be because the adjustment you entered is registered only for regular tax and not AMT.  What you need to do then is to make the same basis adjustment for AMT.
