Get your taxes done using TurboTax

There is $37 on 3a which is negligible IMO. I understand too that if there was an error in the TT software that the boards would be blowing up.  Still I do not understand how there can be such a large difference [$324] between what that tax table says is the tax on the amount on line 15 and what TT determines is the tax due on the amount on line 15; regardless of how one arrived at the amount on line 15.
