Unfortunately, there is no automatic step to remove duplicate photos from Google Photos. However, by following the instructions in this article, you can find and remove duplicate photos manually, either through the Google Photos website or the mobile app. Keep in mind that Google Photos has a built-in duplicate prevention feature so if duplicate photos show up in Google Photos, there's a good chance they're due to you also backing up the photos in question to Google Drive.
