Income Tax Return

Hi All

My questionis related to ITR. As from last two year, i m filing online return & for coming AY 2011-12. i m planning to do same. But in this FY 10-11, i have changed job during this year. As my old compny deduct TDS as per the exemption limit & new company is donig the same. I hve informed to my new company about my previous salary but they deny to deduct more TDS. If i will deposit the advance tax by my own then how could i reflect the same in online return & if will make more investment then declaration to employer how could i claim tha investment in the online return.

Please give your opinions

Thanks
