Your state income tax and your federal income tax pretty much work the same. It all just comes down to what your taxable income for each amounts to, how much you owe, and how much you’ve already paid (usually through employer withholding as defined by W-4).
TurboTax.com can electronically file your federal and state returns and it tracks the progress of your e-file so you know what’s happening now and what will happen next.

And here I just want to express my distaste for state income tax forms with instructions similar to:
1. File your federal tax return first
2. Write down your taxable income amount from your federal form
3. Write down the amount of your federal refund. (If none, or if you owe taxes to the federal goverment, write 0.)
4. Add the amounts from lines 2 and 3. This is your state taxable income.
