If I understand you correctly (and I'm not sure I do), I think you may have over extended your TS spindle. Lock down the TS so it won't move. Then grab the center/spindle with your left hand and try to push it back into the TS while turning the handwheel with your right hand in a counter-clockwise direction. If that doesn't work, you will have to explain your problem in a little more detail.
On mine, if I loosen the lock handle too much the whole spindle will just revolve instead of retracting. If this is what's happening just turn the spindle till the groove is back in alignment what the lock handle and turn the lock handle till it's back in the groove and you should be good to go.
