Itr

For A.Y. 2017-18 I got a notice u/s 143(1) from income tax dept. according to which I’d not paid the self assessment tax. Although the self assessment tax was paid by me but it was not reflected in Form 26 AS. I had all the documents so after a tedious process the Form 26AS was updated. After that I’d responded to “Disagree with demand “ and gave all the pertaining details. I’d inquired from IT helpline and CPC Bangalore also and according to them the ITR is processed and I didn’t have to do anything. But my ITR login page is still showing it under Response to outstanding tax demand. Please advice what is to be done so that the matter is sorted.
