I need a cash advance on my taxes

Likely the program won't start until January 2025 and if the prior years are any indication, Turbotax would have to make the offer for an advance to you. You don't apply 

Sorry…TurboTax does not have any refund advance loans at this time.  For the past several tax seasons, there have been refund advance loans during January and February.  Those loans had to be offered to you, and no money was issued until the IRS accepted the user’s e-file.
