if you're not seeing ES summary page and vouchers in your return it could be that Turbotax has determined you don't owe it.
In Forms mode go to Open Form then "Estimated Tax Payment Options" if the form "Est Tax Options" is not in the list by default and that will show you what is going on. Turbotax by default will assume safe harbor calculation based on 100/110% of 2025 tax and that your 2026 withholding will be the same as 2025.
Under Other Tax Situations / Form W4 and Estimated Taxes you can work through options if needed.
