touchpad is little bit down in right side

There are two "levels" of clicking that your trackpad can do. One is the normal click, but if you continue pressing a little harder it will do an even deeper click, called a Force Click. A force click feels like you're clicking even lower down on the trackpad.

Is it possible that you're doing that deeper click on the right side of your trackpad? If that's the case, and this is a feature you don't like, you can disable it in Settings -> Trackpad and disable "Force Click and Haptic Feedback."

A Force Click is a trick of the mind. It uses vibrations and sound to make it feel like you're click more deeply that you really are. So if your trackpad is physically lower on one side, and you can see that with your eyes, it is likely physically bent and will need to be repaired. If you recently bought your MacBook it will likely still be covered under warranty. I recommend chatting with Apple Support in that case to see what they can do for you.
