how to file local earned income tax if work out of state (PA)

So I live in PA and work in NY

on my W2 there are two pages,

one for NY with box 16 showing NY taxable income, i.e., NY state wage

one for  PA with box 16 showing PA taxable income, i.e., PA state wage

according to my employer, NY  takes all, so, NY state wage becomes my total taxable wage, and PA state wage is 0

 

Now i am filing my local EIT, i live in Bethel Park, PA, with a tax rate of 1.4% of the state wage 

my question is which state wage should i use for this EIT? NY state wage or PA state wage, or the sum of both?
