As you are entering your information, you will enter your
state of residence as of the end of the tax year. Then, there is another question that asks if
you lived in another state during the
year. You will answer Yes, and enter your previous state of
residence, along with some additional information.
Depending on the states and whether you had income in both
states, you may be need to file a part-year resident state tax return for both
states. TurboTax will help you determine
if this is required based on your inputs for the Federal return.
