Turbotax will implement the official IRS forms, instructions and worksheets.
However, be aware that when Turbotax is first available in November, it will almost definitely include at least some 2024 calculations that will not be updated in time for the first release. Turbotax will release updates throughout the tax season, and will not allow you to file if one of the forms or calculations you need to use has not been updated. For most taxpayers, Turbotax will be ready to file by about January 15.
