Schedule G-L Help for New York and Pennsylvania

Hi, my husband and I lived in PA for 10 months while working for a NY based employer (which doesn't have a reciprocal agreement with PA). In mid-Oct we moved to NY and continued working for the same company. As we are doubled-taxed while we were living in PA, we have to apply for Schedule G-L for getting credits for the tax we paid in NY. I have a few questions


1. In Turbotax, for filing Schedule G-L, they ask to fill out 2 columns, "New York Amount" and "My Amount". What is the difference between those two? for an example if I earned $80k for the whole year from a NY-based employer and out of that I earned $60K while living in PA for the same employer, then do I have to enter $60k in both "New York Amount" and "My Amount"?


2. What comes in line 4a and 4b in Schedule G-L?

 

Thanks for all the help!!!
