State tax filing
If you're filing a Part Year Resident return for New Jersey, you'll get a screen in the NJ interview asking you to allocate wages that belong to NJ. This amount will show on the Allocation Worksheet for Part Year and Non Residents, which carries over to the NJ 1040 P2, Line 15.
If you feel this is not being handled correctly in your NJ return, you could delete NJ and step through the interview again to repopulate the forms.
