Revised return u/s 139(5)

On filing of the revised return u/s 139(5), the original return filed u/s 139(1) shall be deemed to be withdrawn and substituted by the revised return. Revised return basically means that you have filed your I-T return for this year and want to make changes in the return which you have filed. 

In case if the revised return is filed online, the assessee is required to furnish the 15-digit acknowledgement number of the original return. On receiving the revised return, the I-T department searches for the original return which is retrieved using the 15-digit acknowledgement number.

Thank you.

My true issue is - can I still file a revision under 139(5) or should it be diffrent?

My original was filed, electronically, under 139(1). and the original has been processed and refund credited - so will 139(5) still apply?

thanks
