NJ Non-Resident Gross Income Too High

[anon40]

For my NJ non-resident tax filing, TurboTax is automatically adding all states income. I am a resident of MA and my MA state income already includes income earned in other states as well, so the NJ total wages are $15k too high, and my tax liability is inaccurate. How do I stop the program from doing this? My NJ gross income does not look correct.

More details:

1. I am filing in CA, MD, and NJ as a non-resident and MA as a resident. 
2. My total federal wages (box 1) and MA wages (box 16) are both $108K
3. NJ box 16 is $4777. Box 1 is $108K.
4. I think Turbotax is summing all state wages under NJ non-resident filing to show $123K total wages.
5. My 401K contributions total $3300 - not all of these were contributed in NJ since I work in multiple states. (I know these are not tax-deductible under NJ, but I still don't need all my state incomes being summed).
