This seems to be the nonoperative phrase: "and that we are just suppose to remeber the amount and put it on schedule 1 as other income."

That's what one person proposes. That's not in any instructions.

If you go back to prior years, there is nothing different about Form 8915-D or -C or -B that you would expect in 2021, so why do so many people have this anxiety and think something different, overlooked, or specifically manual will need to happen for the 8915-F?

People: Let the IRS get the form finalized, and let the programmers figure out how it fits into the software. It isn't only the -F. Slow your roll.
