Can’t remember how to edit my home page

I’m not a developer, but somehow learned enough to actually develop my own site. Problem is that it’s been a long time since I’ve changed anything, and now I can’t figure out how to change “2020” to “2021” on the Home page. The Home page editor shows no text, so the text must be somewhere else. Any ideas where to look?
