challan

Hi Respected Sir/Madam, I have received CPC outstanding tax demand notice on 11-Mar-21 for amount ₹55750 for AY20-21. But I had paid the amount with challan and updated in ITR while filling in Dec-20 itself. Yesterday when responding to outstanding tax demand I wrongly accepted Demand Is Correct. But then realised I made mistake. Please suggest what I have to do to get relief from outstanding tax demand? Currently status of ITR is successfully verified. I have submitted rectificatio..
