Married filing jointly - living in different states

My husband and I are filing jointly, but in 2021 he lived and worked in Nevada for over 6 months and CA for 3 months. I moved to GA in Dec. 2020 and we own a home there (he is on the title). He established residency in GA when he was home in November 2021(Driver's license). I don't know how to handle the state taxes. Nevada doesn't have state taxes, but CA does. Should we file separate state taxes?
