It depends. If you worked only in your resident state there is nothing to enter. If your state has a reciprocal agreement with an adjacent state there is nothing to enter.
If you worked in a nonresident state and were taxed on money earned in that state, you may have a credit for taxes paid to another state.
The credit for taxes paid to another state on the same income is used on your resident state because they do not want you to pay taxes twice on the same income. As the resident state all worldwide income must be included.
The credit for tax paid to another state on the same income will be the lesser of:
If you do qualify for this credit you will need the amount of income taxed by another state, and the amount of the tax liability on that income in the other state. If the nonresident state is completed first, TurboTax will carry the information. You can also enter it when asked if you did do your resident state return first.
