Huf itr filled but not send itr V

My father was having HUF . 

He is no more. 

He was the karta of HUF. 

Before the death of my father he had filled HUF itr electronically. 

But he was not able to send ITR V to banglore CPC. 

HUF income is below taxable limit. 

I want to leave as it. 

As there are too many complications in filling revised itr of HUF. 

Please reply.
