Yes...all of the income earned in NC is NC taxable...assuming you physically worked there.
(...........and you are not talking about a Military W-2, or are the civilian spouse of Military person posted to NC...different rules for those).
Make sure you go thru the Nonresident income allocations in the NC Nonresident interview. Only the NC W-2 wages are NC nonresident income...the other stuff on the extra allocation pages would normally be all zero's....unless you also get income from rental properties you own in NC, or own a business located in NC.
