After you file

I'm in the same boat and put that I could be claimed as a dependent, but my mother did not end up claiming me. My question is, what was I supposed to click in that section if none of the boxes pertained to me? The boxes are "someone can claim: you as a dependent, your spouse as a dependent, spouse itemizes on a separate return or you were a dual-status alien". None of those pertain to me, if I go through amending my 2020 returns, are you allowed to just leave it blank?
