Cancelling AP Scores from 2020

I’m trying to figure this out at the moment, and I’ve run into 2 problems.

  1. The current form Collegeboard give out only lets you list tests taken in 2021. I’ve found the one from 2020 that lets you put in scores from any year, but I’m not sure if they’ll take it.
  2. The form asks which tests you took late and which you took on time, but there’s no way to tell. I don’t remember which ones were late in 2020.

I’ll be calling on Monday, but I was wondering if anyone here has any clue about this; it’s pretty confusing. I’m aware that you don’t need to cancel scores in most instances, but I have to in mine.
