CPC clarification for ITR 4 e-filing

Hello, I am working as a Doctor in a hospital, but we are paid professional fees. So assuming the same I have e-filed ITR-4 in the income tax website. While filing the ITR-4 the TDS says the "Schedule TDS 2 Tax deducted at Source other than Salary".So hence "B4 Income from Other Sources" was filled up and the ITR filed. But got an email from CPC saying there is mismatch (vi) Income as per Form 26AS which has not been included in computing the total income in the return-143(1)(a)(vi) Sl.No | Income as per IncomeTax Return |Amount paid/credited as per Form 26AS | Variance (i) (ii) (iii) (iv)= (ii) - (iii) The column with "Income as per IncomeTax Return" says is Zero and the column "Amount paid/credited as per Form 26AS" is the income amount. CPC is expecting a response from me. What should i respond or Shall i e-file again? Please suggest. ~Thanks
