Get your taxes done using TurboTax

So the IRS doesn't need them. That's fine. But if you have numbers in boxes 12,14,15 or 17 they are required for state taxes. In the TTX program if you don't enter those amounts, then those state/local taxes will not be deducted from your federally taxable income nor will they be reported on the state return. That means you'll double-pay taxes on the state and/or local return.
