Rectification of incometax return

Does he want to carry forward loss or pay more taxes out of gains??.  

if he is not getting any refund it is Ok.

But the ITR-1 is wrong - He should have filed ITR-2.

Sir 

He filed Return already and he  got refund also,after that he wants to rectify his return is it possible

am asking is it possible to revise or rectify of return after processed of original return.

ITR-1  does not have a Capital gains schedule.

Had he filed ITR-2 then rectification is possible. But CPC normally sends to Juris AO.

I am not  sure whether he can file revised return with ITR-2. 

Not sure whether it will be acceptable.

he has to file ITR 2 now, rectification is not possible as original return is filed in wrong format. if the amount is small then just ignore or file ITR 2 as revised return.
