Hello,On the blog page, I'd like to take the "categories" widget out of the sidebar and place it right under the heading that says "Blog". I registered a new widget area in functions.php but I don't know where to place the widget on the blog page. Thank you.

Thanks for reaching out.
You'll need to add it to the template of the blog.
See here for a nice guide: https://buckleupstudios.com/add-a-new-widget-area-to-a-wordpress-theme/
The blog is generated in a small loop in the index.php file.
Let me know how it goes.
