your Y axis is inverted (its printed back to front)
It is an endstop and probably a direction issue
Where is your Y endstop?
If its at the back of the machine this is Y min endstop, plug it into the Y min endstop plug on your controller and configure #define Y_HOME_DIR -1
If its at the front of the machine this is Y max endstop, plug it into the Y max endstop plug on your controller and configure #define Y_HOME_DIR 1
Then check the direction of movement Y+ should move the bed towards the front, Y- should move the bed towards the back
If you need to change this find #define INVERT_Y_DIR if it says true change it to false, if it says false change it to true
