I agree, it seems like the code in Box 7 should be 'P', but it is '8'.
If I enter code 'P' instead in Turbo Tax then it gives me a message 'It looks like you may need to amend your 2021 return'. It doesn't show the amount as Other Earned Income (which I believe is correct since it was reported in 2021), but I don't know if I can enter something different than what is on the 1099-R.
