Technically, you must file an SC return because you were a part year resident. If you had no income while an SC resident (11/26/19 to 12/31/19) you will not owe any tax to SC and should be OK to skip filing. But, coming from TN makes that choice less likely. If you came from anywhere else, you could file as a full year
resident of that state which might satisfy the SC tax people. But, TN doesn't have a traditional state income tax.
