I just reviewed how I entered my dates in my return, using the forms view with the "1116 Comp Wks" form, Part 2, (which is where I entered the dates). The column heading there says the format is mm/dd/yy, but the dates that I entered were 12/31/2020. That's the way they showed on that form after I entered them.
And on the actual "Form 1116 (COPY 1)" form, which I did not attempt to edit directly, the dates displayed as 12/31/2020 in Part 2, Column l (that's an ell, not an eye), and the amounts showed up in Column q. There was no date format specified on this form for Column l.
And, again, since I had two different international investment accounts of the RIC variety that each paid foreign taxes, I had to enter both of them as if they were separate "Countries". After doing these steps my eFile was accepted by the IRS and the state of CA.
