How to declare or include hra allowances of previous employer at the time of efiling ?

Hello , 

I have declared HRA with my previous employer and have not submitted original rent receipts at the time of relieving from the company . Previous employer has issued FORM 16 without exempting HRA allowances but conveyance allowance . I would like to include my HRA allowances for 3 months which is 33k around . How can I add this amount in eFiling ? 

Regards
