Ok, gotcha on the extension payment vs. estimated payment. I'll make that payment today.
For the sake of argument, let's say I had not made an extension payment and did indeed make a late estimate tax payment on 1/29. I am still confused on how I provide this to TurboTax.
I went through the TT interview for estimated payments and filled in the late payment on 1/29. Going to Forms mode, I see it on the "Tax Payments Worksheet" line 5 (with a 1/29/2024 date). When I go back to Interview mode and go through the Underpayment Penalties interview, I'm ending up basically at my original issue.
I get to the screen titled "Date of Payment". It says "Enter the date you paid or will pay your balance due. We use this date to determine the underpayment penalty amount you'll be charged. If the balance due won't be paid before the extended filing deadline of this return, you can leave this blank." Well, with a late estimated payment, I did pay it before the filing deadline. However, if I put 1/29/2024 on this screen, I again get "Date you'll pay the balance due cannot be before the current date".
The difference I in behavior I'm experiencing here is that the 2210 penalty worksheet changed and having/not having the date only results in a $8 penalty calculation (b/c it does/does not remove the 4th payment penalty). But I'm still stuck with the original error message that I opened this thread for. I'm at a loss how that would be reconciled in TT or how that isn't a bug if on the same screen it even indicates past tense "date you paid".
