Tax refund says sent to my bank, bank says they have not received it

[Michelena]

If the Where's My Refund?  tool shows stage 3: (1) Return Received, (2) Refund Approved, and (3) Refund Sent, with the date provided, it can take up to 5 days to hit your account. It all depends on your financial institution and how long they take to process deposits. If nothing comes in after 5 days, check again with your bank and if they don't have any information, then contact the IRS at 1-800-829-1040 for further information.

Hope this helps!
