State tax filing

Sure- I live in NY and work in NJ (part of our income in NJ (married filing jointly)). 

During my State review the screen asks me to "Check this entry. IT-112-R(NJ): Tax Amount - TP should not be greater than the tax imposed by other state.

 

I tried reading the form. Part of what is confusing me is do I use the taxes state income tax number from W2 for each state or is there some "amount of income tax imposed" by that state that might not match what I show as paid in on my W2?
