Those estimated tax payment vouchers print out for a convenience, and you do not have to use them.
TurboTax will automatically include four quarterly 1040-ES vouchers with your printout if you didn't withhold or pay enough tax this year. This is just to head off a possible underpayment penalty on next year's taxes.
You also may get these vouchers if you're self-employed or had an unusual spike in your income this year. For example, if you sold stock or you took a large distribution from your retirement plan.
You're not required to make estimated tax payments; TurboTax is 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.
