How to delete the hack code on my wp frontpage?

I can see the code when I visit my page domain.com and right click and view source.

My question is, where is this page in my cpanel?

I can’t find the code in wp editor, so I need to edit via cpanel.

I’ve somebodys dumb iphone injection across all my sites, like 40 sites. Im hoping its just a small piece of code on all my frontpages.
