When you begin a state tax return in TurboTax, the program will transfer all relevant information from your federal return to the state topics. You don't need to re-enter the information for any states in your return. However, if you have information that is specific to one state, you will need to enter that during the state interview. There is no available upload or transfer tool.
We recommend that you complete any nonresident state interviews before you begin your resident state return.
