If you neither lived in nor physically worked in NC during the tax year, then your work income is not subject to NC income tax.
In order to obtain a refund of the incorrectly withheld NC tax, you must file a non-resident NC tax return, on which you show the NC withholding but report zero NC income.
If your employer does not withhold South Carolina income tax for you, then you must make quarterly estimated tax payments to SC.
