Domains and DNS

Hi, when I set up my first site a couple of weeks ago I got the details for A and C details for custom DNS to get my domains to point to my new site and this worked well once I amended the records on the site that provided the domains.

When I set up my second site, I chose the option to enter the Domain on publish on Zoho as it said it would get the domain to correctly point to the site made through Zoho.

It hasn't so I want to set it up manually myself and can't find the details.

I would appreciate help with this
