The reciprocal agreement between OH & WV only applies to full year residents. Assuming you physically worked in OH, while a WV resident, you need to file an OH non-resident return and a part year resident return for both WV and SC. You report all the 2 months of OH income on your OH return. You also report the 2 months OH income on the WV return and claim a credit for the tax paid to OH. Report the income earned in SC only on the SC return
