too much back on state taxes

[bangerta02]

I only worked in New York for 2 months before moving to New Jersey and have tried multiple ways to adjust my wages from the state but it still seems to be filing as if I earned all of my income in new York. I dont want to make a mistake filing and end up in trouble over this

New York part year residents are taxed on all income while they were New York residents and income derived from New York sources while a nonresident. The tax is calculated by determining the total tax liability on all income (federal AGI), then prorating it based on the ratio of New York-source income to total income. 

You will see the allocation ratio on the New York IT-203.
