Hi 11Rickasks44,
It sounds like you need to sync Contacts with iCloud. I want to help.
Let's make sure you're signed into iCloud with the same account you used on your other devices:
Sign in with your Apple ID - Apple Support
If you're logged in to iCloud with the right Apple ID, check to see if Contacts enabled in Settings > [your_name] > iCloud > Contacts.
If Contacts is turned on for sync with iCloud, you'll want to make sure all contacts are being displayed in the Contacts app.
Open Contacts > Groups > Show All Contacts if you see that, then tap Done.
In the event you're still not seeing your contacts, you will want to check on the iCloud website to see which contacts are shown there. You can login and check the contacts on your iCloud account here:

Let me know if that helps.
Thanks for using the Apple Support Communities.
