I left the "s" off the http in my domain name..What government entity do I go through to fix it? Or is that $15 too?

If you mean you purchased a domain at a domain registrar then you own domain.com - the http or https is done at server level - https being ssl secured so you have both if you see what I mean - the server/software just needs setting up with an ssl certificated so you can run the site on https instead of http

 

See the following guide on switching your site itself to https. The software itself ignores this in the licencing check, so thats not something you need to change on file.
