So is it an automatic column or a manual column?

Sounds like the part in the column that follows the shift action has moved from the park position.

On edit - on brother's c10, we cut the rod that went from the quadrant under the hood and welded it to the steering column webbing so it wouldn't move. A usable solution but the steering wheel won't lock any more.

Does the action of turning it to the start position feel normal and engages the starter? If that feels normal can you put the gearshift all the way in park. Does it have a good feel from reverse to park.Can you push the lever up towards park while try to turn key? If you can your linkage is probably out of adjustment. If you still can’t disconnect the linkage at transmission and try again. There is a possibility that the ignition switch rack is broken in the column.

Do you get ignition lights/buzzer?

As Mike said, Look for a problem with the rack. Mine broke some years ago, real pain.

Sector gear insider could be broken.
This is a 74 non tilt column with a tooth missing that caused similar problems.
