@Irahs --
Since you moved in 2021, you'll be filing two part-year resident tax returns. Allocate your earnings as a MI resident to MI; allocate the remainder to SC. MI will then refund any excess taxes withheld. You will have to pay any taxes due to SC.
For 2022, you'll have to file a non-resident return for MI, allocating zero income to MI, in order to have the 2022 withholdings refunded.
