IT Return for an unregistered Trust

Hello All,

I have a case where the IT Return was filed on 20-12-2019 for an unregistered Public Trust. The return was filed even though the tax is not paid and for that instance even the amount that was appearing to be payable is at MMR.

So what could be done now? Should i not verify such return and prepare revised return where tax payable will be put down to nil?

What if the return is not verified? Do i still get the demand notice or defective notice?

Please guide me in this regard

Thank you
