I have completed by 2025 tax return online. Now I want to complete an updated W-4 form. How do I open the completed tax return to create a new W-4?

After filing, open your return

On the left sidebar

1. Scroll to Other Tax Situations
2. Other Tax Forms
3. Form W-4 and Estimated Taxes. 
4. Select "Start" or "Update" 
5. Answer "Yes" to changing your withholding, 
6. Then follow the interview to generate a new W-4.

There is no Other Tax Situations section in the menu bar.  The only items available are Tax Home and Documents.

If you select Tax Home all the other options on the menu will open and you can follow the steps provided by JohnB5677.  You can also use TurboTax W-4 Calculator.
