TDS Return filing

We deduct tax frm our employees' salary during these last few months in a F.Y. & need to file return with the IT Dept accordingly.

Now, the Tax consultant who handles the above work is not upto the mark & we r trying to learn the filing procedure ourselves.

Can any1 plz appraise me abt the Forms, Due dates & the download/upload procedure with the incometax.gov website?

Thanks a lottt.
