Hi, I filed my income tax for assessment year 2012-13 using my digital signature. However, I did not enter any values in sheet "IT" (Tax Payment Details) section. I received acknowledgement however it is reflecting taxes paid (7e) as 0 in acknowledgement.

I do have challan details which i want to add to that xml file. Can i get a chance to modify and enter those details and get new acknowledgement copy?

Can somone please help me regarding what can i do now ?
