Machine is stuck in high hitting position and won't move

Check that the button hole lever is not somehow stuck in the back position.

When you turn it off and back on, does it show the needle position correctly on your control panel? If trying to reset the needle position doesn't do it, then you may need to take it for service. Check to make sure it's not set for a stitch design other than straight stitch or that you stored the needle position in Memory.

Try adjusting the pressure on the presser foot, or make sure your feed dog are in up position and moving forward

I suspect your Super needs some degunking internally, the old dust,, fluff and oil dries up inside and goes hard and this can eventually gum up unused parts. You could take off the top and have a look, usually a couple of screws holding down the top blue cover. Use a cotton bud and denatured alcohol and clean up around the needle centring wheel internally, cleaning and some gentle movement may free it up.

the machine may need to be serviced to see why the needle position won't
move

sounds like a part is damaged or jamed, the machine needs to be checked
to see what's wrong with it

it's possible that something has come loose or broken, it needs to be serviced

Is your needle position selector stuck? Try moving the dial back and forth a few times. Have your oiled your machine lately? You manual is available on Singerco.com and is free to download. Good luck

I finally figured this out. The feed dog switch in the back was not hitting anything when I moved it back and forth. There is a screw on the underside of the machine that I tightened. It seemed to do the trick. Thanks.

stuck the whole machine the needle did not move .needle and wheel handle both are stuck
