Featured Video Widget

I installed the featured video widget and when I go to the options Featured Video page HERE and click it goes to this URL:

https://americansvow.com/wp-admin/options-general.php?page=videosidebar.php

but it comes up can’t find the page because apparently I don’t have the videosidebar.php file. I’ve looked everywhere in my folders but can’t find it anywhere. Anyone got this file you could put up a link to or tell me how to get it.
