The 1040ES vouchers are optional. If you expect to owe at least $1000 at tax time next year it is a good idea to use them and make estimated quarterly tax payments to avoid a penalty at tax time next year. But you are not required to use them. You can also make estimated payments online at the IRS site if you want to. The one you must use if you are mailing a check or money order for 2022 tax due is the one that says 1040V.
