State tax filing

if your federal return reflects the UC subtraction on schedule 1 line 9, then it's been included in the SC return since it starts with federal taxable income

 

Taxpayers who filed a South Carolina tax return before May 18, 2021, should review their return to determine if the correct amount of unemployment compensation is reported in federal taxable income. If it isn't correct, file a Form SC1040 with a Schedule AMD (Amended Return Schedule). The “Amended Return” box on the front page of the SC1040 must be checked.
