Amended 2021 Fed eFile rejected! TurboTax email explanation doesn't make sense to me!

After help from this community I amended my previously eFiled 2021 Fed return. TurboTax didn't detect any problems so I went ahead and eFiled the amended return. Then I received an email from TurboTax that it was rejected and the rejection email makes no sense to me. The rejection email is as follows:

 

Email begin:

The good news is, we can help resolve the issue easily, and work with you to update and resubmit your return as soon as possible.

 

What happened:   IND-078 - If 'TotalPaymentsAmt' in the return is equal to 'TotalTaxAmt', then the following must be equal to zero if an amount is entered: 'OverpaidAmt' and 'RefundAmt' and 'AppliedToEsTaxAmt'.

 

Next step:   We'll help you get this updated on your amended federal return and e-file.

 

To update your return:   Once you've opened your return in TurboTax, the details about what needs updating will be displayed.   From there we can walk you through making the updates you need and help you e-file your return. If it isn't possible to e-file your updated return, we'll make sure you have everything you need to print and file your tax return by mail.

Email end.

 

That's the jist of the email message. I don't know what it means and when I went back into TurboTax and opened the return, TurboTax did not behave the way the email said it should. There were no details displayed about what needs updating (as the email said there would be). So, there was no walking me through making the needed updates so that I can resubmit. So, I am stuck. I don't know what needs correcting and TurboTax is not behaving as the email said it would so I don't have a clue on how to correct it.

Thanks.
