Hi, May be the following can be useful:
1. Login to Traces-Go to Defaults Menu-Select Request for Correction Tab-Enter Particulars and follow the procedure-Click Add challan option and select the challan (Amount paid with interest) from the drop down.
2. After successful addition of the challan a token number will be generated and request will be sent to ITD. Check the status of the same by -Go to Defaults Menu on Home page-Track Correction tab. It takes normally 24 hours to update the status to "Processed" mode.
3. Once the status is changed to Processed mode, download the consol file from Traces, in this file you will be able to find the added challan, Make the necessary corrections and upload the revised return.
Further you can refer the detailed procedure on the Traces website under etutorials.
Thanks,
Shloka
