How do I find Apps and Data on my iphone? I need to download icloud back up to my new phone

The 'Apps and Data' page you are referring to only appears during the initial setup of the device. If you are at the home screen currently, you have to erase the device and start from the beginning to get the option to restore from a previous backup.

You do not need to locate "apps and data" to restore from a backup.
