Can’t Locate Calendly Code to Remove It

I removed the Calendly plugin months ago but can’t find the code left on my site to remove the darn thing. I finally located the code by right clicking my site’s home page and choosing to view page source; however, I have poured over all parts of my sites actual theme editor files but not found the code anywhere. Wouldn’t it be nice if there was a simple search bar to locate it? Alas, no dice.

Given the source file above, can you tell me where on my site’s theme editor files it is?
