Yes---you have it. Your GF does not have to wait for you to amend to mail her return, she can mail her return when it is ready.
When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as certified mail so you will know the IRS/state received the return.
Federal and state returns must be in separate envelopes and they are mailed to different addresses. Read the mailing instructions that print with your tax return carefully so you mail them to the right addresses.
It takes a long time for the IRS to send letters---and since you will be amending it is unlikely that you will even get letters.
