Deductions & credits

Look at your Form 1040.  On page 1, is Line 37 $0?  If not, is there anything besides Lines 7,21,22, and 37?  Is Line 21 the same number as Line 7 (except Line 21 is negative)?

On page 2, what is on Lines 44,45,46, and 47?  Is there anything on Lines 57-62 (if so, which line)?
