Are you asking about a refund anticipation loan?
TurboTax is testing a cash advance option for some users, but it's probably not the typical refund anticipation loan you're used to thinking about.
It's only available in 15 states. And only after an efiled return has been accepted by the IRS. It is linked to a Turbo Prepaid Visa Card.
This offer is a test, available for a limited time only, and specific eligibility criteria apply. It is not offered to all filers. It will not become available as an option until January 29.
See this FAQ on more info and how it works.
