Note bubble appeared today in the upper left corner of my profile photo. Is there a way to get rid of it?

It’s a white rounded rectangle with “Note…” in it. I don’t use Facebook much, but I never saw this before today. If I tap on it, “Share a thought…” appears in a white rectangle. Can I get rid of this note feature that suddenly appeared? I don’t know why it’s there, and I don’t want it. It’s obscuring part of my profile photo. If anyone has info or answers, thank you in advance.
