As far as
1099-series forms, South Carolina only requires that you attach 1099s that show
South Carolina withholding.
For other forms or
documents that may need to be attached to your South Carolina return, please
see "BEFORE YOU FILE" on page 4 of 2018 SC 1040
INDIVIDUAL INCOME TAX FORM AND INSTRUCTIONS.
If you're efiling through TurboTax, any required documents will be automatically attached to your efiled return.
