ERROR K-1 AMT basis at beginning of year override does not work

[merck3630]

Screen 20 Passthrough K-1s, Basis Limitation (7203), AMT (if different), Stock basis at beginning of year, if different is NOT overriding the AMT beginning year basis in federal or state basis worksheets.  Upon further study, the number I enter appears to be ADDing to a secret number stored somewhere in the system.  Please correct in a future release of Lacerte.

I was able make up numbers for the AMT basis at the beginning of the year until the basis worksheet output matched values in the AMT beginning of the year basis value from last year. 

This is not the way to make this work, but a reasonable workaround until a fix is found and published.
