Hello Bitbucket

When i want to add ssh key in my personal settings, there is message "Someone has already added that SSH key." Could you help me to fix this thing.

Thank You

This happens when you try to use the same key for two different accounts.  You should not be doing this, a key should belong to a single account.

There's no easy way to find out which of your other accounts may have already uploaded the key, and hence no way to remove it.

The solution, assuming you don't want to use the older account, or can't find out where it is, is to generate a new key for the newer account and add that instead.
