My rejection email included the following message,
"/Return/ReturnData/IRS1116/ForeignTaxCreditSource/USTaxWithheldOnDividendAmt - Data in the return is missing or invalid. Please double check your entries."
I am glad I came upon this thread after having my return rejected 3 or 4 times. Following advice I read here, I change the date entry in Form 1116, Part II - Foreign Taxes Paid or Accrued, (l) from "various" to "12/31/20".
My return was accepted!!
Good luck to all who are stuck in this little minefield!
