Per your reply, I have completed the "Send tax file to agent"
Token number: 122158462-33418694
Please see the second NJ-COJ form for taxes paid to the Pennsylvania municipality. You can see that the current value in box 9a of that form is correct, but only because I modified Column B, Row B in the Other State Income and Tax Smart Worksheet. If you remove the numbers from Column B, you will see that the value in Box 9a goes down significantly, which reduces the credit and increases my taxes due to NJ.
I look forward to hearing back on why this is happening.
