flex?  The refund advance closed for 2024 in Feb 2025.   The refund Advance usually starts in January and just when you are ready to file. And only if they offered it to you. You can't self select it. Then you don't get it until AFTER your efile is Accepted by the IRS which is usually late January.

Footnote says…..Funding occurs after IRS acceptance. IRS accepts returns starting late-Jan.
