The desktop download software is already available, so if you need TurboTax Business for 2024 you can purchase and download it to a Windows PC and get started on your 2024 return, but understand that there will be many updates to the software. You cannot actually e-file a 2024 return until late January, when the IRS begins to accept 2024 returns.
You have not actually described your business, though---so we do not know if you need TT Business or if you just need online Premium to complete a return with a Schedule C. If you are a sole proprietor, you can also use any version of the desktop download in order to prepare a Schedule C.
Again....you cannot file a 2024 return until late January 2025 at the earliest.
