Tax error code 662

Hi...I've Received a defective return notice under tax error code 662 telling that refund claimed but income not offered. But all incomes have been offered. Out of 20 Lakhs receipts, on 13 lakhs Voluntary contributions TDS u/s 194C has been deducted. Therefore showed under Schedule-VC. Other than this, going through 26AS everything is in order. So should i change the schedule VC to Receipts from Main objects to rectify the defect. Is it ok?

Thanks in advance
