A Minor difference in your school address and jee mains form and class 12th board result is unlikely to cause issues in jee advance registration or councelling. As there authorities mainly verify essential details like name, date of birth and roll number. Since the correction window has closed, can prepare a supporting document such as school report card that confirms the address as per board records. And you can also call on JEE advanced helpline for guidance but generally, address discrepancies are not critical for verification during councelling.
