Finding my subdomains

My domain is hosted with Cloudflare. I have a subdomain I was using in Clickfunnels but it’s not working. Being non-technical, I don’t know how to find the problem. Is my subdomain, which I believe I made in Cloudflare, disabled for deleted? How do I troubleshoot this problem?

Clickfunnels is a very popular platform here. There are many posts for Clickfunnels setup.

I need to find out where I created the sub-domain. Where do I look in Cloudflare to see what sub-domains I have?

It’s all in the DNS tab.

OK, the sub-domain isn’t there. Is that likely to mean I created the sub-domain in Clickfunnels? I’m not sure that’s even possible.
