If your employer is withholding taxes from the state you are working in, and you live in a reciprocal state you need to have employer correct W2 so it doesn't happen next year. There is no need to override anything in the program, as you just file a non resident return for the state that taxes were withheld from, and a resident return for where you live. At the bottom of the federal worksheet part X1 is the info for nonresident tax info.
