Once you e-file it is just like putting a letter into a postal mail box --you can't get it back. You must wait for the IRS (not TTax) to reject or accept your return --ONLY the IRS can make that decision. The IRS requires you to PRINT and MAIL your amended return (form 1040-X and supporting papers).
Put another way you can't amend a return that has not been accepted --because the IRS doesn't keep a return until it is accepted; therefore there is nothing to amend. If your return is rejected you need to CORRECT it not amend it.
Perhaps some terminology/definitions would be in order:
AMEND:- your return is what you do AFTER your return has been filed and accepted
by the IRS and/or state. (No additional charge)
CHANGE:- your return is what you do BEFORE your return has been filed --simply go
back to the respective information and change it as needed.
CORRECT:- your return is what you do AFTER you attempted to file your return and
it is rejected by either IRS, or state --again, simply go back to the
respective information and change it as needed.
Above all DO NOT DO ANYTHING until you find out if your return is rejected or accepted.
