Why is my gross compensation coming up higher than what it really was and how do i change it?

I lived in PA but only worked in NY the entire year of 2016. However, box 16 has a different amount on the w-2 from PA and the w-2 from NY. Why is that?

NY and PA taxable income are different due to the difference in each state's laws.

For example, in NY, contributions to a 401k plan are taxable by the state.  In PA, they are taxable.
