Hi EmperorFPM,
Can you explain what you mean by a homepage section a little more?
Are you asking how to add content to your homepage? If you want your homepage to have specific content on it rather than a list of your blog posts, you’ll want to set your Homepage Settings (which can be found in the Customizer > Homepage Settings) to “A static page” rather than “Your latest posts”.
You can create a page called Home or something similar and then edit that page to add your content using the new block editor (or the classic editor, if you’d prefer).
Here is a screenshot of those settings: https://imgur.com/a/rZGUMUD
