If you're referring to the Estimated Tax (ES) vouchers generated by TT, by default it is using a calculation for minimum tax payments based on 2024 information.
To avoid underpayment penalty for 2025 you either need to pay 100% of 2024 tax (110% if AGI > 150k), or 90% of 2025 tax whichever is smaller (the 'safe harbor'). TT defaults to the 100/110% of 2024 option, assumes any withholding from 2024 remains the same in 2025, and the difference is the estimated tax vouchers it generates.
If you had a large one-time income event in 2024 you don't expect again in 2025, this default estimated tax calculation will likely be more than you need to pay in estimated (or final) taxes.
To adopt the "90% of 2025 tax" option, go thru the interview in Other Tax Situations / Form W4 and Estimated Taxes which will ask for more information on your expected 2025 income and withholding.
If you are on desktop you can also see more details on the ES voucher options and calculation in Forms mode, "Est Tax Options" worksheet.
