Based on the limited info you provided, you file a part year resident return for both states.
But It depends, more info is needed. What is your intent when you say "It is only temporary"? Are you working there? Why were you in that other state for 22 months? School is a special situation? Moved (returning) to your hometown state is a special circumstance. What is the state of you car registration, voter registration, drivers license? Did you work in the 22 month state? What state(s) did you file taxes in 2020 (filed as resident, non resident or part year resident)?
