If you have NOT filed the 2023 tax return then you only need to correct the information that you have entered.
If you have filed the 2023 tax return then you will need to amend the 2023 return that was filed.
You will have to wait for the IRS to either Accept or Reject your filed federal tax return.
If the return is rejected you can make the necessary changes and e-file again.
If the return is accepted you will have to amend your original tax return. An amended return, Form 1040-X, can only be printed and mailed to the IRS if the original tax return was not e-filed. The IRS will take up to 16 weeks or longer to process an amended tax return.
Before starting to amend the tax return, wait for the tax refund to be received or the taxes due to be paid and processed by the IRS.

If your tax return has numerous errors, and you have not filed it, and you have not paid the TurboTax fees, you might want to just clear the entire tax return and start over.
