The IRS says in general to allow up to 5 days for any direct deposit due to variations in different bank procedures and times, but it usually doesn't take that long. Someone who has received theirs on that card may post their anecdotal experience.
Are you sure the IRS has released the funds? You can check at the IRS WMR tool.

However, there may be another link in the chain that you can check in the meantime 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 if the IRS has actually released the funds, we can tell you how to check on the funds at the level of the intermediary company (SBTPG.)
