To do a sidespin topspin stroke you start with the basics for a backhand topspin. Then you drop the end of your racket towards the floor to get it at an angle. If you contact the ball like this you will generate sidespin.
I suggest you take a look at the Forehand Sidespin Topspin.Apply the same principle to the backhand..
