See my post above, @msliming. You need to type a NJ line on the W2 in question. You don't need to alter the W2 you've received. This is only so that the New Jersey portion of the return picks up the income. When you mail in the return, you will include the W2. But keep proof of how much income you earned at that company that you must claim to New Jersey, in case New Jersey asks.
