No, separate assessment order is passed for each year. hence you can claim the TDS in that year only. And you should claim the refund for the same.
As per section 139(5), the revised return can be filed before the expiry of one year from the end of the relevant assessment year or before the completion of assessment, whichever is earlier.
For FY 2009-10, AY is 2010-11. One year from the end of AY 2010-11 is 31-3-12. Still you have chance to file revised return.
Go and visit the Assessing Officer. He will tell the way to claim your TDS.
