Cant find Testimonials

Hi,

I’m not able to find the “testimonials” in my customizer, nor figure out where I can upload text/info for it. I’m not sure if I have a plug-in that somehow messed with the theme, but I did just deactivate any plug-ins I added that were new. I am using wordpress.org. Any help with this?

Thanks!
