Need small advice from a Tax consultant

Job ID: 34358794

Budget: ₹600 – ₹1,500 INR

Hi,

I had filed ITR 4 without paying the tax(Tax amount was 26730)
Then, I filed a revised tax and paid the Tax amount (26730)

Now, I have tax intimation which shows under s/c 143(1), the total tax amount is 37912.

I don't understand from where this amount has come.

I clarification on this would be grateful.

I have attached the intimation order.
