Sir, I have a business of Computer maintenance and repairing with no professional certificate. I filed ITR-4 for AY-2018-19 with business code 14008 at section 44AD. My gross receipt is 4,52,000 and declared profit is 2,80,000 and FD interest is 1,53,000. Now I have got a notice with error code 86. What shall I do ? Some says fill ITR3 but other says fill at section 44ADA. Last year I filed with code-0714. Please help.
