Response to demand.

On 17/11/2021 a demand of ₹600 was advised to me which I paid on 17/11/2021 itself but it's response on efiling portal could be submitted on 28/12/2021. The delay in submitting response was non updation of paid chalan on efiling portal, while paid challan with minor code 400 was correctly showing in my 26as. The demand of ₹600 with interest of ₹12 is still showing while I paid it within time. My query, when this demand will disappear from my efiling page.
