You cannot amend a tax return to add a refund advance from TurboTax. If TurboTax offers a refund advance on the 2024 federal tax refund it will not be until after January 1, 2025.
So, if you are offered the refund advance on the 2024 federal tax refund then it will only be paid after the tax return is e-filed and accepted by the IRS. The IRS probably will not start accepting 2024 tax returns until late January.
