I remember that post and actually created a duplicate return doing the deduction rather than a credit so I could compare the difference in taxes and whether it would be worth filing an amended return at a later date. But I don't think I ever altered the "original credit return". But at this point, I'm not 100% sure. I manually re-entered the numbers from last year's return. Glad to hear it was a "me" problem and not a "TT" problem in this case.
