So glad this is being looked into!
I have the same issue of getting my tax return submission rejected by the IRS with the same error message (/Return/ReturnData/IRS1116/ForeignTaxCreditSource/USTaxWithheldOnDividendAmt).
I've applied the workaround discovered on this thread (changed "various" to "12/31/2020" on Form 1116 date paid or accrued), but unfortunately that didn't do the trick for me and the return is still rejected, this time with a new error message:
/Return/ReturnData/IRS1116/ForeignTaxCreditSource/ForeignTaxesPaidOrAccruedDt.
Please help to sort this out...
Thank you!
