Estimated Payment During Shutdown

Has anyone successfully made an estimated payment to the IRS recently?

I’ve only done an estimated payment once before and the money was quickly withdrawn and I received a confirmation email.

This time, it’s been a few weeks and neither of those things happened. I’m wondering if I did something wrong and should try again. Or maybe I just shouldn’t have attempted this payment during the government shutdown (I assumed this was all automated and it’d be fine).
