How do I show this on Turbotax? We are a married couple, but in 2022 one spouse had Ontario as a residence and the other spouse had Nova Scotia as a residence.

Unfortunately, if you and your spouse lived in separate provinces, then you will not be able to prepare your returns together in TurboTax. You would need to prepare your returns separately, as TurboTax will not let you pick separate provinces, or even different addresses.
