And you can then federate your domain with your ADFS environment. If you want to federate it with your on-premise ADFS you would need to move the users and the email domain to a new Microsoft O365 tenant. It is not possible to federate to this system and you will have to buy a license directly from Microsoft and migrate your federation setup completely to Microsoft Office 365 in order to get that kind of control because godaddy does not allow you to go to Office 365 management portal and they provide their own O365 management portal which does not allow multiple management operations. In your case if you are getting redirected to Godaddy SSO then it seems you are using the Office 365 mail plans by godaddy. or it can be federated with any O365 syndicate Network (O365 through godaddy, dell etc.). If it is federated, it can be federate to your own federation service like on-premise ADFS or OKTA, auth0 etc.

In case of managed it means the system is federated with Microsoft federation system and the authentication is managed in the cloud. It will check whether the domain's authentication is managed or federated. The O365 system will check the UPN suffix of your username and redirect you to endpoint which will further try to find out about your domain. When you try to logon to the Office 365 portal it would require you to provide your username and password and any MFA prompt if already setup.
