Once the IRS releases the funds, the IRS FAQ page says to allow "up
to 5 days" due to variations in bank processing procedures and times.
Also, once the funds have been sent, there may be another link in the chain that you can check if you used the following service:
Did
you have any TurboTax fees that you chose to pay out of the Federal
refund? If so, the funds go first from the IRS to a temporary account
at an intermediary bank where the fees are subtracted. Then that
intermediary bank sends the rest of the funds on to your bank (or
card.) If you used that method to pay fees, and once the IRS has
actually released the funds, we can tell you how to check on the funds
at the level of the intermediary company.
