143(1) - TDS mismatch - 26 AS

sir.while processing the intimation u/s 143(1), certain TDS credits are not considered, and the same has been turned in to demand, eventhough the entire TDS credit was appeard in 26 AS. i made grievance to that effect to the CPC incomr tax, but again the same thing has been received u/s .154 kindly advice.
