This kind of impact damage usually means the lens barrel or internal focusing parts have been knocked out of alignment. If you can’t carefully fix it yourself, professional repair is often not economical for an 18-55mm kit lens. These lenses are very common on the used market because many photographers sell them after upgrading, so replacing it is typically the more practical option than paying for repair. Before replacing it, also check that the camera body mount looks undamaged, but based on the symptom you describe, the lens is the likely problem.
