Question on 3 state taxes on W2

[Natti1]

I have a w2 with 3 different state taxes. Part of the year I worked and lived in GA. Then I relocated and now reside in NJ but work in NY. My state taxes for each state may be wrong and not sure how to proceed. Example. My GA is correct earning for state. I question the NY earning and NJ. 

I only live in NJ not work. Lets say I earn 120k a year. I lived in GA for 7 months and NJ for 5. My GA state taxed amount is correct at 70k. Problem is NY is showing a state earning of 120k (which is not correct, I worked 5 months and earned 50k). Now NJ is showing 50k earned as well. 

Do I have to allocate my NY wages down to 50k? leave them at 120k? 

Also when asked to confirm taxable state wages from all 3 states where we check mark to remove duplicates, which do I remove? NJ and GA? or NY? Thank you

When you complete your New York nonresident return, you will do an allocation that shows how much income you actually earned in New York. The return will calculate New York tax liability on all of your income, but will then prorate that tax based on the percentage of your income you earned in New York ($50k/$120k). Leave the wages as they are on the W-2, as this is how New York requires the W-2 to be completed - you'll do the allocation in the NY return section,

Because you lived in NJ while working in New York, you will also have to pay tax to New Jersey on the same $50,000. The good news is that New Jersey will give you a credit for the tax paid to New York to help limit the effects of double taxation.
