I ran into this with TurboTax 2024 on Mac. I spent hours and hours with tech support who had no idea what this was and how to fix it. They were reading the same forums I was and had me try a lot of things including full reinstall, browser flush, ... A ton of unrelated things. There is no "blocked payment" thing. No one I spoke with knew anything about it. They really are not knowledgeable and don't know what they are doing once there is a technical problem. One of them even told me that my license (which I bought from them) was fraudulent!!! I ended up filing Federal online since it did not require payment but a paper copy for the state at the last minute.
However, there is a way to make the payment on the phone and get a code which you can then use without having to go to the payment screen. Unfortunately, none of the 4 reps I spoke with had any ideas of how to do it. Absolutely, the worst support. You may have better luck. Go to the "Help" menu in turbo tax,
Help -> Purchase by Phone -> State efile
Instructions there are good, you give them the serial number on the screen and they are supposed to give you an e-file confirmation code you write in the box and you should be all set after that. Good luck getting someone knowledgeable.
