Urgent - regarding u/s 154

You can file revised return under section 139(5) of Inscome tax act.

Time for filing revised return:

one year from end of relevant assesment year 

                                     or

before completion of assessment

Whichever is earlier.

Therefore you can rectify your return within that period.
