To remove a source from Kodi, follow these steps:
1. Open Kodi and go to the home screen.
2. Click on the gear icon at the top left corner of the screen to access the "Settings" menu.
3. Click on "File manager" from the list of options.
4. You will see a list of sources that you have added to Kodi. Select the source that you want to remove.
5. Click on the source to select it, and then click on the "Remove source" option at the bottom of the screen.
6. You will be asked to confirm if you want to remove the source. Click "Yes" to proceed.
7. The source will now be removed from Kodi.
Note: Removing a source will also remove any add-ons, repositories, or media content associated with that source. If you want to keep any of these, you will need to move them to a different source before removing the original source. Also, removing a source will not delete any files on your device, it only removes the reference to those files within Kodi.
