Notice received from cpc u/s 143(1)

I received intimation from CPC u/s 143(1) as my ITR income is not matching with form 26AS.

I purchased a car in the month of october worth 1050800.00. Ths amount is appered in form 26AS as Amount Paid/Debited. The car dealer also deducted TCS (10% amount) i.e. 10508.00

Now my concern is that in the notice received from CPC, the amount 1050800.00 is appeares under income from other sources.

Please help me in this case to send reply for the notice.
