Remove all except NJ.  NJ requires software programming to not automatically exclude income reported to other states from being transferred to the return.  However, if you don't select these boxes, your NJ income will be reported much higher than what it actually was.

@DanielV01 Thank you for the speedy reply.

Once clarifying point: If select everything except NJ, as you've mentioned, the amount reported on line 15(a) is equal to the my State Wages (i.e., Box 16 on W-2) - which is significantly lower than the amount reported in Box 1 on W-2.

However, per the NJ-1040NR, it seems like Line 15(a) should include all income; which i assume means total wages - which would be the amount in Box 1. 

Hopefully that makes sense.

Thanks again in advanced!

Unfortunately we don't have access to your return, so we can't see what information the program is giving you nor what you have input.  However, your premise is correct.  New Jersey uses Column A to determine how much they would tax all of the income, and column B is to prorate to the amount of income attributable to NJ.  You might want to contact customer service to make sure your inputs are correct and, if so, then if the program is calculating correctly.
