Domain Release/Transfer Issue

I wanted to put my domain on Wix, so I released it. I am trying to figure out how to get it back, because it is still registered to me. However, it is showing as a used domain, so I can’t. I can see it on my Cloudflare account, but when I try and manage it or transfer it, it says I don’t have a domain I can transfer or goes to a 404 page. Help!
