i have 4 vouchers to send payments but no dates when is 1st payment due

Those four 1040ES vouchers are optional---they can be used to make estimated quarterly payments for your 2025 tax.  If you expect to owe at least $1000 at tax time for your 2025 tax return next year, using those vouchers and making payments during the year can help you avoid a big tax bill and/or an underpayment penalty next year.  You are not required to use them.

And...they are NOT for using to pay your 2024 tax due.   

Your tax due is on 1 voucher labeled 1040 V.    It was due April  15 .   Do your 4 vouchers look like this?   They say Due  April 15, 2025 at the top and a big 2025.  They are estimates for NEXT year so you don't owe so much again.  You can ignore them if you want.  They don't get sent with your return so the IRS won't be expecting them.
