TDS Challan deposited in Excess so not matching with OLTAS

Dear all

My company has got noticed from Income Tax regarding non finding of certain Tds collected and paid mentioned in TDS Return but not matching with OLTAS. On enquiry i found that since challan has been deposired with Bank in excess than actual amount due, it is not matching with information on OLTAS.
What should be my action now? Shuld i claim the excess tax deposited? And whether can i state that excess TDS was deposited for no reason?
