There are two tiny screws on the side of the bobbin case. When you are holding the bobbin case with the bobbin down the screw on the left is the screw - 200592 - that holds the tension spring on.
The screw on the right is the adjustable screw -201016 - for bobbin tension,
The screws are NOT the same.

These are really Tiny!

Sometimes the spring on the bobbin case can become damaged. These are replaceable

Bobbin tension can be affected by an improperly wound bobbin, especially a bobbin that is ‘over-wound’ with too much thread. This will keep the bobbin from turning freely in the bobbin case.
