Unconsed challan

u can use it

 or carry forward it for tds purpose

if use for itr purpose then fill return then u will get refund 

Hi

Consumption of earlier paid challan against subsequent liability will amount to TDS paid before due date for which Income tax department would better appreciate the act as they got taxes much in advance than warranted and would never penalise you by levying any type of interest.

Thanks and Regards,
