Travel Nurse - Taxes paid to another state

Hello! I am a travel nurse with a home tax location of Oklahoma. I worked a contract in South Carolina last year. When I am filing for my state return it asks if I was taxed on income from another state. I listed yes and it has me complete my Adjusted Gross Income and Tax Paid for that state. How do I answer this and as a travel nurse should I even be completing this section? Thanks!
