Get your taxes done using TurboTax

you'll need to show more detail. 

 

Have you answered all the questions that TT asked?  Did you enter how much you have already received in stimulus (it is at the very end of the interview process).  Maybe just a coincidence, but $1200 is also the amount of stimulus per tax payer. if you didn't say you already received $1200, TT is going to put $1200 on Line 30 of Form 1040
