I filed my taxes but want to start over on my federal

[xmasbaby0]

"I filed my taxes.."    By "filed" do you mean you e-filed?  If you e-filed you cannot start over.

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 about 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

Once a tax return has been filed and accepted, the only way to change it is to prepare, print and mail an amended return form 1040X. DO NOT change your original return until you start the amended return. An amended return should not be filed until your original return has been processed and you have received the refund if you are getting a refund.

Amended returns must be printed and mailed by you. They can't be efiled and TurboTax does not print and mail them for you. In normal times, they take 16 weeks to process. It is taking much longer now because the IRS is not processing any mailed returns and hasn't been for some time.
