Incorrect TDS Amount submitted in Belated Return

Hi,

Whiling filling my ROI of FY 2009-10, I have missed TDS deducted on certain incomes, while the income has been correctly shown in my ROI.

The ROI is filed as a belated return, thus could not be revised as well.

I presume, at the time of Assessment, the Income Tax system will show the credit of TDS against my PAN, thus will be granted refund of the same. Please comment of this understanding and also let me know the way to correct the same ( I think I can do it u/s 154)
