How do i edit the date in the column of period with the emp

Dear Sir,

One of our employee objected his Form -16. i.e., actually he joined in our organization on 01/06/2013. But I prepared eTDS return (24Q) in his column the period with the employer as on 01/04/2013 to 31/03/2014 instead of 01/06/2013 to 31/03/2014 So, please any one can tell me how can I edit this date. He is demanding me to issue him a correct Form No.16 with correct employment period.

Please help me.
