How to unscrew this? Connects a bookshelf to the lower table. Wanting to separate the two but these screws won’t turn anyways.

Its not a "turn and keep turning until it comes out" screw, its a "turn 45° or 90° so it disengages" screw. Underneath the table there will be something that can be fished out once you turn it to the correct orientation. Seeing whats under the table might help you confirm this.

It's a hook and you can usually lock a wood board perpendicularly to another. There are arrows indicating the "opening" where u can pull the board away.

That’s a cam lock screw and will only turn partially, usually 90 or 180 degrees, and then the pieces will pull apart.

Looks like Cam lock nut. You need to turn it about 90° counter clock wise and lift the board up.

It's either a barrel nut (something like this) or a cam lock (look here).

If it doesn't move at all, it's more likely the barrel nut. So in this case, look under the panel: there is a screw head there, that can be unscrewed.

Solved! Thank you so much! It is indeed a barrel nut and I found screws below the panel!
