I authorized full payment when I filed2024 returns. why did my turbo tax documents include payment vouchers if I made payment in full?

Did you get the 4 1040ES payment slips? They are prepayments for NEXT year. They are optional to pay. The 1040ES quarterly estimated tax payments DO NOT get sent to the IRS or state with your return. So they won't be expecting them. If you are receiving a refund or low tax due and Turbo Tax prepared the vouchers then your tax liability was probably reduced by credits. Turbo Tax is very conservative and doesn't want you to owe too much next year. They might have printed out if you got a one time large income this year. Like if you took a IRA or 401K distribution or had a large capital gain. They are just a suggestion.
