What exactly is the procedure for a deductor with regard to filing of tds return in form 24q for a previous year in which case itr has been filed and processed? To make it clear,  suppose if deductor forgot to include few tds details for ay 2011-12 can it do so now?  Also is there some role of tax commissioner in the aforementioned case? Respected experts,  plz help!
