TDS Query

Dear All

My client deducted TDS for a Vendor on an Invoice amount 100,000 @10%. on 28th July 2009. As per Act, he deposited the TDS amount as on 7th August 2009.

But on 18th August, a Debit note was raised on the Vendor for 50,000. The TDS was also reversed on the debit note.

Now my question is :

How to treat the extra TDS deducted?

What to show in Form 16A?

Pleae advice.

Thanks & Regards
