Did you click that big orange button that said “Transmit my return now?” If you did that, you cannot do anything to fix it yet. The IRS will begin to accept/reject 2020 returns on Friday, February 12, 2021. You have to wait for the email that tells you if your return was accepted or rejected. If you do not see an email, check your spam folder.
You cannot change or add anything on the return that you just e-filed, nor can you stop it. It is too late, just like when you put an envelope in a US mailbox on the corner.
If you left out a W-2, a 1099G, or a dependent, or a 1099 etc…DO NOT change your return while it is “pending.” The changes will go nowhere.
Now you have to wait until the IRS either rejects or accepts your return. If your return is rejected, you will be able to go into your account and make the necessary changes to your tax return and re-submit your return.
If the IRS accepts your return, however, then you have to wait longer until it has been fully processed and you have received your refund. THEN you can prepare an amended tax return and mail it in. 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. return.
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
If you have already filed your return, you cannot retrieve your e-filed tax return (It is like dropping a letter in a USPS mailbox). You'll need to wait for your tax return to either be rejected or accepted, if it is rejected you can add your Form 1098-T, correct any other errors on the return and resubmit it.
If it is accepted, you will need to amend your return to include the Form 1098-T.
Please be aware that Form 1040X will not be available in TurboTax until February 18, 2021, but once it is available, you will be able to prepare and e-file your amended return.
Please see this TurboTax FAQ for instructions on how to amend your tax return in TurboTax.
