have taken the print of Triplicate Challan by clicking on the "Print" option. I have to deposit the cash in a branch of SBI through this Challan. How will I re - enter the system to submit my transaction details of the fee if I log out of the system now?

No need to submit your transaction details of the fee. To know the payment status login once again using ‘My Application’ menu after 2 days of payment. If ‘Your payment has been confirmed’ message is being displayed in the Remarks column. Then you are allowed to generate your application. If ‘Your payment has not been confirmed’ message is being displayed, then you need to wait till the confirmation message appears.
