UPDATE: I was able to pay the IRS online using Direct Pay. Am hopeful that turbotax didn't actual send a payment
I have the same problem, 2018 taxes are due on 4/15/2019 and neither TurboTax nor the IRS show any payment made even though the extension was approved. I don't want to duplicate a $10K+ payment but neither do I want to incur fines and late charges for not making the payment with the extension. The only thing the TurboTax email stated was "Your 2018 Federal Personal
Extension has been approved!" I hope TurboTax improves this issue.
