How to redirect a subdomain?

Question

URL Handling

Hello.
Please help, there is a domain "site.com.ua", hosting costs at home. The next question is, I want to make a subdomain "admin.site.com.ua" and redirect to a completely different site. Where I bought the domain, they say that I would create a subdomain and ask the hoster for a redirect.
I am the host myself. What do I need to write in the hosting parameters? In fact, the essence of the issue is very difficult to describe.
