What is the status of the 2023 federal tax refund on this IRS website? - https://www.irs.gov/refunds
If TurboTax offers a refund advance for tax year 2024, it will not be until after January 1, 2025. If you are offered an advance on your 2024 federal tax refund, you must select direct deposit of the refund and e-file the 2024 federal tax return. Then you have to wait for the IRS to accept the 2024 tax return before the advance will be paid. The IRS normally does not start accepting federal tax returns until late January.
