I recieved a 1099 NEC with CT state income in box 7 and state payer information in box 6, but I am a non resident and did the work from my full time home in IL. Because I never went to or performed any work in CT should there be state income listed? If I meet the CT Non Resident Gross Inome test, does this mean I need to file a CT state tax return, even if the work was done from my home in IL? Seems to me the payer should have left box 7 blank and just used only box 1 instead since nothing was done in CT?
