Yes, I had my e-file return also immediately rejected for a Form 1116 error. It was pretty cryptic message from TT and I had no real clue how to fix it because TT couldn't find anything to change or anything that was wrong. I did change the Part II Date Paid from Various (which is correct and successfully done in prior years) to 12/31/2020. As I found this as one of the work-arounds in this chain.
So far my e-file return has not been rejected so it looks (potentially) good as my prior attempt was rejected immediately.
