I think the 2025 estimated payment vouchers are separate from your 2024 payment and any plan for that.
To avoid an underpayment penalty in 2025 you need to have paid thru withholding or timely estimated taxes, either 100% of your 2024 tax (110% if AGI > 150k) or 90% of your 2025 tax, whichever is smaller (the 'safe harbor' amount). By default TT will calculate ES vouchers for 2025 based on paying "100% of your 2024 tax" and assumes your 2025 withholding will be the same as 2024, and the difference is made up by estimated tax divided into 4 equal quarters. If you go thru the interview questions under Other Tax Situations / Form W4 and Estimated Taxes you can provide estimates for 2025 which will likely then trigger the "90% of 2025 tax" option and reduce the vouchers to a more sensible level. The "100% of 2024 tax" method is useful if you expect a significant increase in taxable income in 2025 e.g. Roth conversion.
You will be emailed from the IRS regarding your payment plan for your 2024 taxes. The vouchers are for next year - you can toss them if you don't need them.
We'll automatically include four quarterly 1040-ES vouchers with your printout if you didn't withhold or pay enough tax this year. We do this to head off a possible underpayment penalty on next year's taxes.
You're not required to make estimated tax payments; we're just suggesting it based on the info in your return. If you feel they're not needed for next year's taxes, you can shred them.
