What is my RSS feed and how to delete unused widget box

Hi, I just do not know what my RSS feed address would be to input into a social plugin. I am kind of new at all of this. Any address that I do input, just brings up my site. My site is https://www.housekaboodle.com

Plus, I also want to delete unused Widget boxes created within my Theme (Headway), so I wonder do I do that through wordpress or through my Theme (Headway). I don’t see a way to delete the boxes within either wordpress or Headway. The box I am referring to is not any of the widgets themselves active or inactive, but I am talking about the Title boxes created to put the widget into for example Main Widget or Right side Widget would be the Title. I have 4 boxes not being used and want to delete them.

Thank you for any help,
Sue
