Icloud - how do i find

You can use an internet browser and log into www.icloud.com and see some of the synced data (e.g., iCloud Photos, iCloud Drive, iCloud Notes, and other synced iCloud data such as Mail, Calendar, Contacts, and Reminders).

You cannot view the contents of iCloud Backups; you can only use the backups to restore a device or setup a new device.
