Are you referring to the 1040ES vouchers that were included when you printed your return? Those are not required---using them to make estimated quarterly payments is an option. If you expect to owe at least $1000 at tax time next year, you can use them to make payments in order to avoid a big tax bill next year and to avoid an underpayment penalty. Nothing about them is sent to the IRS. You can choose to use them or you can shred/ignore them if you do not want to make quarterly payments.
