assuming you are a SC resident, the return starts with Federal taxable income which would include the income/expenses from the Federal K-1 interview form. the only things that might show up on the SC return separately would be adjustments to the federal amounts.
On the "Info Worksheet" of SC Individual form under Part IV Other Information you must check "Use South Carolina I-335." This will generate form I-335 which will enter information automatically. This should save you (or refund you) 3% of your Business income. (I got this from my Accountant.)
