Its 21 days from when its accepted not approved! But some can take longer if you filed with credits like eic since those funds cant be released til after February 15. So if u have eic and if u filed ur return and it was accepted by the irs more then 21 days before the 15th u will not be one of the 9 out 10 filers that recieve there redund within 21 days obviously . One ur refund is "approved " they give u date and its usually less then a week not 21 days.
