Demand Notice for return filed under new scheme

Pradnya (student) (217 Points)

26 August 2022  
I had filed ITR 4 under new scheme for AY 21-22.. In May I received a demand for an amount which is exactly the difference between amount calculated under old scheme and new scheme.
I had replied to the notice after 30 days with the issue but there is no further response from CPC.
Should I put a rectification request for the return?
