Hello Tracey Clausen,
Welcome to Microsoft Community.
After seeing your thread, I immediately tested it in my Surface device.
When I'm not connected to a Typer Cover or keyboard, the "trackpad" option doesn't show up in the "Bluetooth and Other Devices" option.
But after I connected the Typer Cover or keyboard properly, when I turned the Settings option back on, I could see the "Trackpad" option in "Bluetooth and Other Devices."
Official information can be found at the following link:

Could you please tell me here what generation of Surface Go you are using? In what cases can you not use the touchpad properly?
Best Regards,
