TurboTax is not offering refund advances at this time. They usually offer refund advances in late January and February, but we do not yet know what will be offered in the upcoming filing season for 2025 tax returns.
You can't get a refund advance until you know that you are getting a refund, and how much it is. You have to first complete your tax return to see your refund. You cannot do that until you have your W-2 and the 2025 software is available.
