Related Posts and Social Sliders, need to get rid of

Hello,

I’m honestly not sure if these are plugins or default features, but I cannot find a way to hide the “RELATED POSTS” without the thumbnails (below) and the small social icons at the bottom.

For the related posts: The “related posts” above (with the thumbnails) is through JetPack. Otherwise I have no related post plugin and can’t find anywhere in the setting, appearances, or editor to edit the RELATED POSTS below it.

For the icons: I’ve deleted all social icon plugins I had and unchecked the “share” button in the post editor. They’re still there.

I’m using Genesis 2.5.0 with Babette child theme.

Thank you for any help you can provide!
