I just realized I made a mistake on my tax return which I submitted early this morning. How do I correct?

Since your return has been submitted- please wait - if it's rejected for some reason, you can make a change and re-send the return.

If your return has been submitted and accepted- you will have to amend; the return is mailed; takes about 16 weeks to process. Here are amending instructions.
