Get your taxes done using TurboTax

Thank you so much.
Please confirm this summary:
In the NJ return, 30% of my total wage (NJ wages) goes into the box labeled "Double-taxed income while a resident of NJ".
On the same screen, the "Tax paid to NY" is calculated as (NJ wages/NY taxable income) x NY total tax liability.
Based on those two figures, TT then comes up with "Credit for tax paid to NY". It's about 20% of the "Tax paid to NY". Not sure how TT calculated that credit.
Does that look right?
In the NY return, I allocated 70% of my income, including wages, to NY.

 

Just one other question. You may not have an answer for this but my W-2's are puzzling.
1) In previous years, my NY W-2 had exactly the same wages for both the state and NYC. That made perfect sense. This year the NYC wage is about 12% less. That makes no sense to me.
2) In the NJ W-2, the state wage box (box 16) has about 13% of my annual wage. I have no idea where that comes from. Of course, I entered that figure into TT as the W-2 info so the New Jersey return calculated my NJ tax liability based on that figure, not the 30% of my total wage. Obviously that works to my advantage but I'm concerned that something is not right. Box 17 has only 35 cents.
