Be careful if you follow the instruction posted by SteamTrain in above to allocate your NC wages because TurnboTax will rollback you change after it done with "Review" but before "File". That is a defect in TurboTax NC State return because it change or update some tax forms after TurboTax finish the "Review" on all Federal and States tax return forms, and post message saying it "Confirm 100% accuracy", but then on next step of "Summary" (or "File" if you click "File" button instead of "Continue" button to skip the "Summary" step). That is very "dangerous" because TurboTax makes change in silent after users already confirm their enter data and TurboTax already passes the Review on the tax forms, such might lead to some wrong tax forms submitted to NC Department of Revenue and get some trouble, like audit.
TurboTax rollback all the change made by users on the columns of "Payer's Name" and "Wages" on the section of NC Wages Allocation, but it doesn't rollback users' change on "Status". Therefore, the best way to update your wages Allocation is to change "Status" to "Not NC Source Income" for all the initial entries created by TurboTax, then add your own NC Wages Allocation on the blank. Please know, all the entries of "Not NC Source Income" (or "Not NC Resident Income") are ignored by TurboTax and those entries are not shown on any tax forms or worksheets.
Also, as I already mentioned in my posts above, you should enter the part of Federal Wages (W-2 box 1) in "Wages" column, not the State wages (from W-2 box 16), because in many cases, state wages are higher than federal wages, especially in the companies with great pension, retirement plan, and health benefits, otherwise, you would pay more tax than what you should pay.
