2020 Federal return rejected due to allegedly missing foreign tax credit data

For the first time ever, my e-filed Federal tax return has been rejected 😪  I filed using the desktop computer version of TurboTax Premier.  The email message from TurboTax states the following:

 

/Return/ReturnData/IRS1116/ForeignTaxCreditSource/ForeignGrossIncomeAmt - Data in the return is missing or invalid. Please double check your entries.

 

Most foreign tax information was entered automatically when TurboTax downloaded my 1099-DIV from my mutual fund company.  I verified the information that I entered manually.  TurboTax found no errors before I filed, and I changed nothing after checking my 2020 foreign tax information and comparing it with my 2019 foreign tax information.  So I don't know what to do other than the e-file the identical return again which would also be rejected unless a TurboTax filing bug or IRS return verification bug has been fixed.

 

I would appreciate any suggestions!
