I moved to North Carolina in March 2023 and the state tax section has asked me to identify which sources of my total federal income are non-NC or NC-sourced income. I have correctly inputted my W2s and have correctly identified which sources of income are NC-sourced, however there is still a $2k discrepancy in what I can calculate as my NC-source income based on my W2s and the income that the NC state tax section has calculated as non-NC income.
