Intimation u/s 143(1) with tcs showing 0 in column assessed by cpc

I have received an INTIMATION U/S 143(1) from the IT department. This shows mismatch in the entry for TCS - it shows the amount I have claimed in column 1 but shows '0' for column 2 (as assessed by IT dept). I had paid TCS to the merchant while buying car and same also shows in my 26AS form. Hence I claimed the same while filing return. How should I proceed in this regard? Your advise is highly appreciated.
