You cannot apply for an Advance on a 2019 tax refund at this time.
See this TurboTax support FAQ for an Advance - https://ttlc.intuit.com/community/refunds/help/about-refund-advance/01/27333
want to know if I can get a refund advance for the 2020 tax year
@ddorothyoz
TurboTax will be offering a refund advance loan —but not until January. And you do not get the money until the e-file has been ACCEPTED by the IRS.You also have to agree to receive your refund on the prepaid TurboTax Visa.
