Form 16A - filing for returns

Hi,

I am student doing project in an organisation as an intern.
I am getting Form 16A in every three months.

I got a query on form 16A.
My organisation has deducted flat 10% as tax from my stipend. Am i eligible for tax refund??

For example: If im getting a stipend of 2 lakhs per annum, they have deducted20,000/-
If i calculate according to tax rules, the should be for an amount20,000 (2 lakh - 1.8 lakh), which is merely2,000/-

So my question is that, if i file ITR-4  and apply for tax returns, will i get a refund for the extra amount deducted (Rs 18,000/-) ????
Is it possible or legal ??

Please give an answer to my query

Thanks
Alex
