To make changes or corrections to your return, you will need to Amend. 

How to amend (change or correct) a return you already filed

[zeycet]

I need to amend my State Tax. In order to do that I guess I need to send to New Jersey state my amended doc. However, I have already got my federal income and haven't get my state refund due to my owe. How can I fix my form? I found 1040-X form and should I fill the form and post it to the New Jersey office?
