Initial (now incorrect) federal return amount has been received. I'm concerned the refile was not acknowledged/lost in the process.
You cannot make changes after you e-file and the return was accepted---change it back to the original that was sent to the IRS when you E-filed and then WAIT.
You cannot amend a tax return that was just accepted. You have to wait for it to be processed by the IRS. Trying to send in an amended return while they are still processing the original return could confuse things and delay your refund for months.
Do not try to change anything on your return now. When you amend, your Form 1040X has to be prepared from the return exactly the way it looked when you filed it originally. You have to wait. Once your return has been processed you will complete a Form 1040X --- which is not yet available --- and submit it to amend the mistakes made when you filed your original return. It takes the IRS at least four months to process an amended return.
The 2020 Form 1040X does not become available until the end of March 2021 (subject to change).
