How do I change my return after it was submitted?

[xmasbaby0]

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, 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. You cannot e-file an amended return.  They have to be mailed, and it takes at least 2-4 months for the IRS to process an amended 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

This post should be updated:  you CAN e-file an amended return (1040-X) now.

Yes, for tax year 2020, the IRS is accepting e-filed amendments (1040X) and you can use TurboTax to do that.   But you cannot e-file the amendment until your tax return is received and processed by the IRS - which they won't start accepting 2020 tax returns until the end of the month at the earliest.    @DeeAnneM
