You’ll find the answer to your problem here, including instructions for eradicating duplicate contacts on your iPhone. With the release of iOS 16, Apple implemented automatic detection of duplicate contact cards in iCloud, with the option to merge them.

Option 1: Remove/merge all duplicate contacts at once
To merge all duplicate contacts and remove them in one swoop, tap on “Merge” at the bottom of the overflow menu. That’s it, all duplicate contacts will be merged in your Contacts with the flash message “Duplicated Resolved”. You’ll no longer be seeing the “Duplicates Found” indicator above the contacts list on the Contacts page.
Option 2: Manually select and merge contacts
In the overflow menu, you should tap on any duplicate contacts that you want to resolve. The overflow menu shows details of the selected duplicate contact. After that, you should tap on “Merge” located at the bottom of the menu. That’s it! You’ve successfully completed the steps for merging the copies of the selected contact into one in your Contacts. You’ll be able to merge and remove duplicate copies selectively. You should tap on “Cancel” at the top-left of the overflow menu once you’re done merging selected contacts. The unresolved duplicates will continue to be shown on the Contacts page as “Duplicates Found”.
