Dear Sir,
There are two ways from you get the challan for the payment:
1). If you have the Service request no. (SRN) of the challan, Direct go to site, and on the left hand side of the home page of the site, there is one tab named "Track Payment Status", click on that, it will ask you the SRN, enter the same, and then it will show that payment has not been done and under that there will be button for copy of challan, you can get the same by clicking the same.
2). If you dont have the Service Request No. of the Challan, login in the site (login with the username and PW with which you upload the form), after logging in, on the home page, there is the option named "Track transaction Status", click it and enter the starting and end date within which you upload the form, means start date 03-11-2009 and end date 04-11-2009 and submit, it will show you all the forms and returns filled by this ID within the above mentioned time period along with SRN, note down the related SRN from the list or copy the SRN and then again go to home page (home page after loggin in) and select the Track Payment Status and enter the copied SRN (Paste it) and submit, you will get the desired copy of challan.
