I have filled my online return in ITR 3 Form for the f.y 2016-17 on 17-11-2017 (belated, No Tax audit case individual ) for claiming refund of TDS but I have received a notice under section 143(1) that tax credit mismatch or not showing in Form 26AS. while when I was filing return I have checked thoroughly that TAN no. And amount of TDS was correctly filled and crossed checked it from Form 26As. Every thing was correct. But don't understanding the reason for not getting TDS REFUND. So I have filled rectification request online today and select reprocessing the return again and checked the box tax mismatch box.
So I want to know how much time it will take to get process online rectification request..?
Or I have to fill revised return..?
