When I just tried that, the IRS Direct Pay tool no longer will accept an estimated tax payment for 2021. The only choice it presented me for the reason "Estimated Tax" is for tax year 2022.
@hanunian If you use the IRS Direct Pay tool, be sure you don't choose the estimates option and mistakenly pay for the wrong tax year.
It will, however, allow one to make a reason "extension" payment there for 2021. Be aware that would be reported in a different place in TurboTax as a "Payment with extension" so that it flows to the correct line, which is a different line than estimates paid. If you decide to go that route, we can tell you how to report an extension payment in your TurboTax program.
