I worked and live in different states, I have 3 W2's, 2 from my resident state and 1 from out of state job, do I input my W2's all at once?
Yes, you do. TurboTax will complete part-year and/or nonresident state income tax returns based off of the W-2 state income information, generally boxes 15-17.
To ensure accurate calculations, we strongly recommend preparing
your nonresident state return before you prepare any resident or part-year state returns. Click on How do I file a nonresident state return?
