Home Full Widget

Hello there,
I purchased the Hello Boho theme, and I’m having issues changing the image behind the Home Optin. Your instructions say this is the “Home Full” widget, but I’m not seeing that widget anywhere in my widget menu. It’s possible it failed to load when I imported all the widgets. 
It’s currently displaying a random featured image I used for a post a while back. I don’t know how to import the widget I need to change the image. Can you help? 
Thank you!
Mary Kathryn
