I see here that you've successfully transferred the domain to GoDaddy:
Our system doesn't automatically know that you've transferred the domain to another registrar, however. Unless you plan on pointing the domain name to another webhost, it should stay in your account, but we should change your upgrade to being a Domain Mapping subscription now ($13/year) rather than a domain registration subscription. Would you want to do that? Or will you be pointing the domain elsewhere? If that's the case, then you should change the Nameservers for the domain with GoDaddy, because for the moment, they are still pointing to your WordPress.com site. Let me know what you'd like to do, and I'll help you through it.
