Thank you. That part I do understand, but where I am confused is the section for NY taxes that says "Tell us about the money you earned in NY" They have amounts prefilled in for "Double taxed income" and "double taxed income paid to NY" but there is a box to correct those amounts if they are wrong. i am not sure if they are right or wrong because the numbers prefilled into the box i have no idea where they came from. those numbers are not on my w2 anywhere for NY or NJ.

The double-taxed income is the income you earned in NY as a NJ resident.  This should be the amount on the NY state line of the W2 in box 16.  However, the double taxed income paid to NY is coming from the NY return, not from your W-2.  You receive a credit in NJ for your NY tax liability, not the amount of tax you had withheld from NY.  If you didn't have self-employment or any NY Allocations, you will not need to enter any information on this screen.  But this screen is only accurate if you have prepared the NY nonresident return first in TurboTax.  Otherwise, the calculations can be off. If you started NJ first you should clear that state return, finish the NY return, and then finish the NJ return.  Then you can trust the numbers and just hit continue on that screen.

Thanks!

You are welcome.
