For 2023 taxes...4th Qtr payment due 15 Jan?
Either
1) print that out from your 2023 PDF tax file (should be in there....you do have that PDF?)
2) get a paper copy directly form the IRS (print it out) (lower down on this page for the 2024 1040ES PDF forms..at least right now)

or
3) Go to the IRS payment site (Direct Pay) and just pay it Online...make sure you select 2024 as the tax year.
