Ay 2020-21 ITR DEFECTIVE

Can I change ITR form in reply to defective return ? Means in reply to Defective Return of ITR 3, Can I file ITR 4 in reply ? Means without choosing Return Revision option can I upload revised XML (ITR 4 XML) in reply to Defective Return ?

Dear Exparts, I File ITR 3 in Offline mode and shows validation is successful. But at the time of submission of Return one error shows that "In schedule BP sum of values entered from 36(iv) to 36(vii) should be equal to sum  of Net Profit declare at Sl.No. 64(id) and 64(iid) in Sch P&L". I declare only professional income of Rs.60,000/- for F.Y 2020-21 which is not require books of account. It is not presumptive or speculative income. How I solve this type of error.
