I also had a Foreign Tax Credit (a small one though) but I was able to file my returns (State and Federal) online today. Yes, I saw this note on the availability of Form 1116 but there was no flags or errors on the final review. I checked Schedule 3 (line 1) and there it was the full amount but there was a catch. It said "File Form 1116 if Required". On the final return, I only found Form 1116 Wks but couldn't find Form 1116 itself. The 1116 WKS will show you the amount carried over to 2022. I am not sure how helpful this is.
Best of luck
