you posted question regarding the touchpad and not touch-screen, anaylor01.
i would look at win-10
pc-settings … from there go to devices … then down to "mouse/touchpad" … finally, click "additional mouse options". this should bring up the mouse-properties interface.
study your mouse-properties interface and see if it allows you to disable the touchpad. for instance … mine offers the user to disable touchpad if a usb-mouse is attached. another feature my touchpad offers is temporarily disable … just by dbl-clicking in top-left corner … but this could be a proprietary toshiba feature.
