My Date of Birth was showing correct in my all previous returns, but in my profile in the new portal, incorrect date of birth has been mentioned. Editing of correct Date of birth in the profile is not accepting. Kindly guide me as my Date of birth was correct earlier and I didn't make any change. There is a question of just one day difference. For 5 Oct they are now showing 4 Oct, the year is correct.
