Here's the REAL solution, at least in my case.
I got the same error message about not being able to authorize my credit card. I tried several cards and all of the other solutions suggested above and nothing worked.
I called TurboTax support [phone number removed]). After delving a bit into my problem, they connected me to Intuit's Finance Department. The found that my account was "locked", but they didn't know why. They unlocked it and asked me to wait an hour for the system to update. An hour or so later, I tried again and my payment was accepted with no problem. Unlocking my account was the important part.
I am using Turbotax 2019 Home and Business. The same thing happened last year and no one could figure it out, so I printed out and mailed my return along with a check. That saved me $25 in e-filing fees, but it wasn't worth the hassle.
