State tax filing

I am trying to file taxes for my husband and I. I moved in the middle of the year from AZ to SC. My husband stayed in AZ until this current year he joined me in SC. He had received unemployment (1099-G) in AZ. When I add that info in it is taking away my SC state tax refund and making us owe SC state tax?? Why is unemployment from AZ making me owe money in SC?
