State tax filing

From your diagnostic token I was able to see what the amount of tax listed on line 24a of Form IT-112-R and it was indeed larger than the NJ tax per your NJ Non-Resident Return. 

If you are using TurboTax Desktop, click on "Forms" at the top right corner of the screen.  Scroll down to the New York section of the forms, click on "IT-112-R" and on line 24a type in the amount of NJ tax of $2290.  That will clear the error in TurboTax Desktop.

If you are using TurboTax Online, please follow these steps:

1. Click on State Taxes, then Your State Returns
2. Click on the "Edit" at your New York Return, then Continue
3. Click on "Credits and other taxes", then answer the question that follows
4. Click on "Update" under Credit for Taxes Paid at Taxes paid to Another State
5.  You should see NJ and click on edit
6. Answer the remaining questions until you see the screen for Tax computed on your NJ return and type in 2290
7. After answering the questions that follow you should have the correct taxes paid credit flowing to your NY return.
