Hi Friends,

I have filled my return with wrong hra calculation and itr V is sent to Bangalore in Oct

after I checked why it is taking more time and realised hra was wrong

in Feb I have filled revised return with correct figures and itr V has been sent to Bangalore and got confirmation of receipt

after above process I got reply from cpc that my first return was defective

I replied with response No and mentioned comment, please consider my revised return for final one and not filled any return related to notice since I had already filled revised return

my doubt what will next step for defective notice

what will be happened now, please explain me

please help me on this
