For FY1819 , as of Nov-2019 , I Received Income tax assessment order did not take into consideration the advance tax payments made for that year and ended up in a demand for 18000Rs.

Advance tax payments have been found in 26AS correctly under the correct major head and minor head , but yet not considered in ITR processing.

Filed a rectification using the option , "Only reprocess the return".

After one month , I received a response with the same demand amount of 18000Rs and reason being that my advance tax payment was again not considered for processing. 

What should I do next? 

Why is the system omitting advance tax payment credit when it is clearly found in 26AS
