Chosen Solution

Whenever I push the left joystick right or left, it respond as if I was pushing it slightly, I tried calibrating the joystick but but had no effect.

This is an effect called the Joy-con drift, originally discovered in the large switch console. Since joysticks in switch lite are mechanically the same, the problem appears. You can’t currently do many things, but nintendo is working on it. For, now you can find more by searching Joy-con drift. Oh, and welcome to the club mate!
