FAQ:  How do I file a part-year state return?

In that FAQ you'll see that TurboTax recommends the following:

"We suggest you prepare the return for your former state first, followed by the return for the state you currently live in.

Important: If you also see a nonresident state return in the State section, complete that return before you work on your part-year return(s) to ensure your tax credits are calculated correctly."
