Self assessment tax credit not given

Sorry for the typo in my original post (now corrected).

Demand received for AY 2020-21

In 26AS, transaction shown un Assessment year 2020-21. Date of deposit is 24-Dec-2020

I have received a similar demand. I have checked the challan details on OLTAS and I can see that it was received by TIN the very next day. Please suggest how I shall proceed?

Thank you for your reply.

I have already verified the details in oltas by searching using cin. The details are correct and same as ITR. (Major Head - 0021, Minor Head - 300 - Self Assessment Tax, Assesment Year 2020-2021 , Challan Tender Date 24-12-2020, Received by TIN on 29-12-2020, same amount, correct PAN)

Under the circumstances, I'm planning to respond to the demand as "disagree with demand" and select "demand paid" option and provide the challan cin details. Though I actually paid the self assessment tax itself which is showing up as demand. Is that be the correct step to be taken?

I suggest that you call CPC to get more info before responding to the demand notice.

I had called CPC, they are saying in a generic way that I'm advised to raise a rectification. However, refused to guide whether only to raise rectification which options OR to respond to demand notice saying disagree to demand OR both.

Would really appreciate any advise from website options perspective. Whether should I response to demand notice while choosing disagree option and supply cin details. As well as raise rectification request with only reprocessing. 

In that case, I think whatever you said (Disagree with demand.....) is the option to choose (because I don't think there is anything to rectify if you have already included this challan in the ITR.

@ BMishra - I am also having similar issue. What's the final solution you went with? Can you please guide me.

In my particular case, I responded to demand notice saying disagree to demand. It eventually reprocessed and rectified. Please cross check your specific case/scenario and take appropriate action..

Thanks, I also provided the same response 

I also was having such an issue, I disagreed, now it is not seen.
