Without knowing what was on the document, it's impossible to tell what action you should take.

However, you may be able to find answers to your questions at the New Jersey Earned Income Tax Credit page; also see the "I received a letter" link on the FAQ page.

It is the NJ EIC document 

[JulieS]

If you claimed Earned Income Credit on your federal tax return and you also filed a New Jersey resident tax return (NJ-1040) in Turbo Tax, you have already received your NJEITC. Turbo tax automatically gives you the state EIC if you got the federal EIC.

If you aren't sure, just check line 57 of your NJ-1040. That is the amount of your Earned Income Credit for the state.
