Removing Featured Image from top of Post

My site isn’t live yet so not sure if a link to it will work.

How can I remove the Featured Image from the top of a post? I want to use it as the post image from the home page, but as soon as you click on the post, the image enlarges and appears at the very top of the post’s page. I want to turn that off so it doesn’t appear there, but will remain on the home page still.

Thanks!
