Hmm. Tough one. Most likely there is something amiss in checking a box or completing the dates, but you have done that. Try reviewing again, if you are like me I sometimes find these things stare me in the face and I don't see them at first until I do a point by point (painful) review.
You have 1099 Box 8 "various" for both dates and RIC, the mutual fund box checked. In Box 7, line b is set to Copy 1 and line C box "A" is checked?
Review your Form 1116 again to make sure Box C (before Part I) is checked, Part 1 line (i) is showing "RIC" and all income is in Column A. To get everything into Column A, you do that back at the 1099. In Form 1116 Part II of box (j) is "Paid".
Another way of tackling this is to compare your 2019 1099's and Form 1116 to the 2020 versions to see what, other than amounts, is different. That might turn up whatever it is that is blocking you. I took me seven failed attempts to find the culprit until #8 went through. If all else fails, calling TT support might help.
