Social Media Share Buttons Gone

I recently discovered that my social media share buttons have disappeared. These are the buttons at the bottom of each of my posts where people can share my post on their Facebook or Twitter etc. When I go into Dashboard the area where I could previously select which social media options I wanted is completely gone (I can't find it anywhere). The only thing I have done that's new is install an RSS feed, which I deleted from my social media icons to no avail. I have no idea how to get these buttons back and I spent two hours on a help chat with Bluehost today and they said they have no idea what could be wrong. They even tried to do a blog reset but the reset didn't work. Please help!!
