Since your tax refund is taking longer than the typical 21 days to receive, see this FAQ regarding What to do if it's been over 21 days.
Keep in mind, In an attempt to protect individual tax filers, PATH act was put in place. This may be causing a slight delay for many tax filers. See this Turbo Tax FAQ for more information regarding Where's my Refund.
