HI RosemaryTlusty,
Thank you for reaching out Microsoft Community. We apologize for the inconvenience this has caused you.
If you already followed all the suggested troubleshooting steps online including resetting the device back to factory settings but the touchpad still doesn't work, then this simply means that you need a new typecover to get this problem be taken cared of. This means that the touchpad of the typecover is already defective if in case you already reset the device. In the event that you haven't reset the device yet, you can reset it but it's best if you can try using another typecover/keyboard so we can distinguish if the existing typecover is indeed defective in that way, it's going to be hassle free for you to retrieve your files.
If this helps, feel free to mark this post as an answer. Otherwise, don't hesitate to respond to this thread if you need further assistance.
Kind Regards,
