Itr return filed wrongly

Dear all,

I have filed ITR 1 belatedly, instead of mentioning u/s 139(4) as 139(1), can any body guide me to rectify this and upload the revised return u/s 139(4) though i treid for it by all means but income tax website is not ready to accept saying error in one or other way.  Even i cannot revise return as only correction that i need to do in the return is 139(4).

Kindly guide us, what is the best approach to overcome this mistake.

Regards,

Vinay S B.
