How to get posts to the right place on my newsletter

I’m having problems getting posts to show up in the section that I’ve identified as Caring Is Organic/Conversations in Caring/Current Posts and Comments (https://www.caringisorganic.com/wp-admin/post.php?post=2661&action=edit) I can’t seem to see what I should be doing to make this happen. My website is http://www.caringisorganic.com.
