Revised return

Hi,

For FY 09-10 , AY 10-11  return filled on 14.10.2010 (in time) return was filled with profit and tds was refundable of Rs 50,000.

The Refund of Rs 50,000 was received on 27-04-11. However, we received one more TDS certificate for Rs 15000 on 31.12.11 pertaining to FY 09-10 which remained unfilled and unclaimed with the original return filled.

Can we claim this TDS certificate and refund for the same by filling a revised return.
