The IRS says to allow 1-5 days after it sends your refund, due to variations in bank processing times. Of course this was a 3-day holiday weekend, too.
Did you have any TurboTax fees, and if so, how did you pay them? If you chose to pay your TurboTax fees out of your Federal refund, that adds another step in the process. It goes first to an intermediary bank, which deducts the fees then sends it on to your bank in a second deposit. If you used that service, you can follow your refund at the intermediary company's (SBTPG) website. If you did not use that service, then this won't apply to you.
