You cannot make any changes to your federal return while it is in pending on the server. If you e-filed the federal return, you have to wait until the IRS accepts or rejects the return. If they reject it you can make changes and re-file. If they accept it, you have to wait until the return has been fully processed and amend it.
The IRS will begin to accept/reject returns on January 29. Sometime on 1-29 or after, you will get an email telling you if the return was accepted or rejected.
If it is accepted -- You have to be able to work from that return exactly the way it was when it was e-filed originally. You will need to use a form called a 1040X.
Meanwhile, DO NOT go in and start changing anything on your return in the system, or you will make a mess for yourself. Sit tight and wait until you see what the IRS does with the return you just e-filed
