Since you have the desktop TurboTax software, try using the What-If Worksheet in forms mode.
- Click the Forms icon at the top right.
- Click the Open Form icon at the top left.
- In the search box type "what" (without the quotes).
- The What-If Worksheet will appear in the window. Click on it, then click the Open Form button at the bottom of the window.

You can do this in the 2024 software, or use the 2023 software and check the box to use 2024 tax rates. If you use the 2023 software you can check a box to copy all the figures from your 2023 tax return.
The What-If Worksheet is not available in TurboTax Online.
