Not sure if all Touch N Sews are the same, but if it has the drop in bobbin, you need to slide the bobbin door open, then close it part way to engage the bobbin winder. I think there may be a mark near the door showing where to stop. Then wrap the thread from the needle around the screw a couple of times and start the machine. The thread should catch around the bobbin and start to fill the bobbin. Hope this helps.
