Extension Question

This is my first time filing an extension due to some circumstances that happen.

I filed an extension for 2023 return. It's approved but my question is about the balance due on an estimated return??

I wanted to more research on what that was but by now I'm sure that date has passed and I figured I was going to get notified on how I would make that payment.

 

I want to file this weekend but well I run into any issues or can I file as normal? Never been through a situation like this filing super late.
