What date do I put "date you became a resident of" if I lived in another state during 2023 but did not change residency? It will not let me put a date before 01/01/2023?

You are in the education forum and students do not live in other states- usually. A student will maintain home with family and is a nonresident in other states. For your home state, enter 1/1/2023 since that shows you were there when the year began. Other states would be nonresident.

For your home state file as a resident, not a part year resident.

there are no dates to enter.

complete the non-resident state tax return first
