When you enter as advised above "my first guess", it allows the full amount paid in SEHI on line 29 ($13,450) which it was not before entering it in that spot, but then allows a full amount of PTC on line 69, ($9,760) which therefore makes the line 29 wrong because now it's not subtracting the PTC from the SEHI.  Aren't I assuming correct that you have to subtract the PTC from the SEHI to get the correct adjusted SEHI?
