Where the sensors are
Most modern systems use two small photo-eye units mounted near the bottom of the vertical tracks.
Simple checks
Clear the beam, gently clean the lenses and look for a sensor that has been bumped out of position.
The issue may be elsewhere
If sensors appear aligned and clear but the door still reverses, the problem may involve wiring, settings, the opener or mechanical resistance.
