appointment at apple store in Omaha, Ne

You don't need an appointment to do that. Just use iCloud: https://support.apple.com/en-me/HT205754

Appointments at the store are generally reserved for troubleshooting problems, not teaching you how to use your phone. Instead, Apple offers free in-store classes you can sign up for, as well as a plethora of information on their website in the form of support articles.

If your iPhone works, you can also download the Apple Store app. I prefer making my appointments through that app.
