saldirj,
Do you by chance have multiple 1099's with foreign tax withheld, that TT combines into Col A? A similar Form 1116 thread has a few people that were finally able to get a successful submission when they split two 1099's info into Col A and Col B (with the same "country": RIC). I wonder if that has to be done along with changing the date from "various" to 12/31/2020. I would try that on my return, but I'm on my 6th (and final) efile attempt. So if my next efile attempt gets rejected, I have to file by paper - which I REALLY don't want to do, since the IRS is WAY behind on processing paper returns.
EDIT: I called the IRS today (their E-File Help Line; I'm never able to get through to their xxx1040 number), and they said that they have no limit on the number of efile attempts/rejections. So if there is a 6 attempt limit with TurboTax, it's TT's own (artificial) limit, not the IRS's.
