double confirm with your database that why you have it twice, which extension is creating it.
try to disable all the install extension one by one and see if it is been resolved.
it is always advisable to backup your db first and the website before making any changes.

You made upgrade from 2.x version right?
You have the answer already...
For 2.x
Beefore upgrade, delete from database oc_api table.
To fix you can delete oc_api table and recreate from opencart sql database or you can delete one of username field from oc_api.

looks like you are running the wrong upgrade or are running it twice.

Is not running twice...it is a bug.
Example:
When you try to upgrade from 2.3.0.2 to 3.0.3.6.. username is added in database because is in opencart.sql table.
Then SQL command not work because is already an username.
Fix1 : Changed alter table with delete command, because username is taken already from opencart.sql.
Fix2: Added delete command before ALTER to delete username then name will be renamed in username and data will be kept (api id, key...)
So in the end upgrade process (upgrade controller) should ignore entire opencart.sql database and use only commands from upgrade models.
