No...NC sourced income refers to income you earned while living in NC......interest, dividends, capital gains, salaries as long as you were physically present in NC at the time. As such, that job that withheld NC taxes was NC-Sourced (if you were physically located in NC when you performed that job). Where the employer's main office is immaterial. (Just because you work for Amazon in Raleigh, doesn't mean that the income is WA state income).
For you, Not NC sourced income is any income you received before you lived in NC, as long as you didn't physically work in NC yourself before your move, (that second part can happen for people living just across the border from NC)
