How to Edit my Home Page

I can’t find where to edit my “Home” page. https://www.breakthroughcoachingadvantage.com

The Home page appears under the Appearance/Theme tab, but not in the list under the Pages tab. I do not know how access the place where it can be edited.

I found a previously closed topic on this subject and this was the response:
“The “home” page is not really a Page. It is created dynamically and you would edit it by changing theme options. Also by changing css and php using a child theme.”

Unfortunately, as a complete novice, I don’t really understand that response. I don’t want to change the theme, I just want to update verbiage and change out the video.

Direction is greatly appreciated.
