If TurboTax notified you that your return was accepted by South Carolina, it should not need to be submitted again. I am attaching a link to an FAQ for South Carolina's refund site. On the site it does say it is normal for it to say the refund is not processing for a few weeks. There is a phone number to contact if you have any issues or need more assistance.
