Q: How do I access the cloud to manage what is there?

Howdy beejay20,

As I undersand it you want to be able to look at what is taking up your iCloud storage. You can do that with the following article:

Manage your iCloud storage - Apple Support

You can also log into your account at www.icloud.com and look at the content you have in there as well. 

Thank you for using Apple Support Communities.

Regards,

Sterling
