Re-verifying via CNAME

Ok, I recently left Shopify and moved my hosting to Hover. I've not gotten mail since. I've pointed my MX files or whatever to the mx.zoho.com on 10 and mx2.zoho.com on 20. I'm not super technical at this. I think I need to re-verify my Cname. What's shown currently is attached to hover, not zoho. But I cannot find how to get the Cname info again. I get to the verification page, but it won't let me back up that far. Please someone, help me. It's vital that I get access to new emails like a week ago.
