Filling hra in itr 1

Hi

As I am a salaried employee with  additional source of income (through bank interest), I am planning to submit ITR1 form. I couldn't submit the HRA proofs to my employer and hence they did not provide HRA exemption under section 10.

Now, while filing IT returns with Incometax department, I plan to get submit the HRA proofs to get the exemption .

When I downloaded the ITR1 excel from income tax website, to my surprize, I do not see any field where I can claim for HRA exemption. 

Is it not possible to claim the HRA exemption at this point ? If it is possible, where can I fill in the amount in ITR 1 form ?

Thanks in advance
