You wrote: "I have already filed the returns (but not mailed)."
What does that mean?? Does that mean you efiled the returns? Or did you want it to mean you haven't actually filed anything at all--haven't efiled and haven't printed and mailed the returns?
If you have printed, but have not filed your return at all (haven't efiled and haven't mailed), we can tell you how to open an unfiled return back up to make changes in it prior to filing.
If you haven't actually filed, how do you ultimately plan to file--by efile or by printing and mailing? If you haven't filed, you can also change the filing method when you open the returns back up.
If you recently efiled, you can't make any changes unless the efiled returns are rejected. But we can tell you how to change your address with the IRS.
We can tell you more when you clarify what you meant and whether you have filed the returns or not.
