Get your taxes done using TurboTax

If you are a US citizen, all your world-wide income is subject to tax in the US and in your home state.  But if you did not have state tax withheld, leave that blank when entering the W-2G.  The income will still be added to your state income tax (if you live in a state with income tax) and the tax due will be added to anything else you owe in that state.
