New user domain question

New user domain question

 I've registered a domain though Zoho and received the notice of sub-domains configured.  A day later the domain still is not responding so I log into GoDaddy and see none of the sub-domains or mx records.  I manually entered the mx records so that email now works through the domain, but still no sub-domains as mentioned in the original domain registration receipt.  Are these not set up through the Zoho domain registration process?  If not, where do I need to point the records (i.e., business, mail, writer, sheet, calendar, docs)
