so if you look at your example, you are only adding another state for the box 17 information, which is the amount of tax withheld for that jurisdiction, but it does not, repeat it does not, duplicate the box 15 to enter income which is taxable in a second jurisdiction. I can duplicate box 17, I cannot duplicate box 15, and your example is likewise not duplicating box 15, just box 17. I need a second box 15 to enter income taxable in New Jersey and New York.
