Get your taxes done using TurboTax

The letters would be on your 1040 tax return by line 1 not on your W2.  Is your W2 box 1 less than 54,000?  Do you only have one W2?  Delete it and re-enter it.  That may clear something out.  Are you a student?   Did you get any 1098 forms?  Those can add a taxable amount to the wages line.
