Excess amount received in form 16a

I had billed a client in first week of April'14 for some Commission. But since the same was pertaning to his march'14 provision he has booked my april bill in March and deducted the tds on the same in his march accounting books. Now after receiving form 16A i am getting diffrence of excess tds receivable due to this issue. Can i claim credit of the same, and in which QTR Q4(13-14) or Q1 (14-15) as i have shown both the income and tds receivable for this bill in April 2014, in opposition to Clients TDS payable in March 2014.

Thanks Members for the help,
