The IRS has not yet announced a date when e-filing of 2023 tax returns will start. TurboTax will let you "e-file" starting on January 4, but your tax return will not really be filed. TurboTax will just hold it until the IRS begins accepting returns. Nothing will be done with it before then. If you submit it early, be aware that you can't cancel it or get it back to make changes or corrections if you find that you made an error or left something out.
