Due to some internet issue i have make payment twice & didn't knew about that at the time of filing of return so filled the return without that challan which is made addition to original challan on 31/3/2018 for F. Y. 2015-16.
Now my question is i have submitted the return still not e-verified; can i claim the refund for that extra paid money for F. Y. 15-16 which is belated return
