tds will only claim in its F.Y/A.Y return. if you have filed return for F.Y 2009-10 with in due date then you can revised your return including your TDS Data or if you have filed belated then you can't revised it.
but you can do is, write a letter to your A.O ward regarding that TDS certificate received lately and attached with calculation format of your F.Y. 09-10. to treat this as refund.
for next time, you have to registered in 26AS so that you don't need to wait for TDS certificate. Just find your TDS deduction from that and file your return without TDS certificate.
