I have a K-1 net taxable income loss of almost $1,000 in South Carolina where I am not a resident. Am I required to file a SC state income tax return?
No per the South Carolina filing requirement for a nonresident:
A nonresident individual must file if the gross income taxable to South Carolina is more than the federal personal exemption amount ($4,050). A nonresident individual files a Form SC1040 South Carolina Individual Income Tax Return and Schedule NR Nonresident Schedule.
