Try Physics.CircleCast() to see the info about the collision.

RayCastHit2D hitInfo = Physics.CircleCast(
    groundCheck.position, groundCheckRadius, Vector2.down,
    Physics.defaultContactOffset, groundLayer);
Debug.Log("Collider=" + hitInfo.collider);

You probably will need to use Vector2.right or -Vector2.forwarddepending on what axes you use in your 2D scene. This vector should point down in the scene. If you have Y axis as vertical, then it will be Vector2.down, and if you vertical is Z axis, then you should use -Vector2.forward I believe.

Also, make sure your groundCheck transform is moving with the rigidBody and not just stands still.
