Tds revised return

Dear sirs, I have filed original return for the F.Y. 2008-09 on due date. But due to wrong pan no. I have revised the same return after say 12 months and same has been processed and some additional demand has been raised like late payment interest form the date of deposit of Tax till date of processing. Kindly note that we have already paid late payment interest with TDS payment. Is it correct. Regards, Shrishail
