@Alex562745 Turbo Tax would have recommended which of the two options to choose from (see @SweetieJean's post) and would have used its recommendation unless you overrode it.
But those two choices relate to part year residency. But from your post the State isn't bying either of those options because they think you were a full year resident....
So I think the conversation is with the State - not with Turbo Tax - and there are some facts missing here.
What state did you live in the other 11 months?
What state did you work in the other 11 months?
Did you file taxes in that other state?
What date did you tell Turbo Tax you moved to SC?
let's start there.
