You itemized so you do have an OBBB adjustment. The federal itemizes State and Local Taxes up to $40k while SC limits the amount to $10k. The program is correcting it for you. You should have a warning that OBBB adjusted your return and you are good to go. Verify your SC return is limiting the state and local taxes to $10,000. SC has extended the filing deadline to October 15. They could make retroactive changes.
You can e-file if your return is correct or you can wait and see if SC changes anything.
