Blog post featured image issues

We managed to get the featured image turned on for our blog posts, but we'd rather they did not show on the blog post itself, and only show on the news section page. How do we make that happen?   This is the page. There is only one blog post for now, but the featured image is missing: https://dirtyboudoir.com/blog/ This is the actual blog post, where the featured image is showing, but we don't want it there: https://dirtyboudoir.com/blog/
