They are to send in extra payments with each one or throw them away, shred them.
The 1040ES are estimates for next year. 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. They are optional to pay. 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. You can ignore them. You might want to adjust your withholding at work so you won't owe too much next year.
