E-Campaign Notice

Can you please help me by replying to above post?

Can anyone tell me if I can still file revised return in reponse to e-campaign notice?

Thank you Sir, I will file revise return. I have one more issue to understand regarding the revised return.

My IT return for AY 2020-2021 (as mention above) was processed on January 4th 2021. I received a refund of Rs 2820/=. Now if I revised my return I have to pay some addtional taxes. So how do I compensate for the refund Rs 2820/= I received. I mean to say that how do I return the refund or how show that I received the refund in revised retrun since now I am liable to pay additional taxes.

Pay taxes by adding refund amount. CPC while processing will adjust refund accordingly.

Thank you Sir. I will add the refund amount to Self Assessment Tax Challan payment.

Does just filing a revised return is sufficient or in this case responding to e-campaign is also required ?

 Technically it looks like 3 possible options ( not very clear should all be done or not ) 

1)file revised returns and don't reply to e-campaign information confirming the same.

2) file revised return and then validate that the information in e-campaign as true.

3)just validate the information in e-campaign and wait for authorities to accept the response and inform us back about the revised return filing 

Please suggest .
