I don't have a way to simulate that since I don't have that Card, so I'm having to guess a bit at what you might be presented. If you have a screen that asks for a code sent to you, be sure you are not closing the original screen when you go to check for a code. If you close it, it probably deactivates the code. Use a second browser window or second browser tab and leave the first interface open.
If you can't reach anyone at the Turbo Prepaid Card customer support, I don't know why. You can contact a TurboTax Support agent for free via messaging at Facebook or Twitter, and perhaps they can suggest something.

Also keep watching this thread and someone may offer another suggestion here.
