Error on payment screen: We are unable to process your order at this time. We regret the inconvenience.

In process of efiling.  For state (Virginia), the charge to efile is $19.99.  I enter payment information (triple-checked it), and clicked "Place Order".

Receive this error from TurboTax:  "We are unable to process your order at this time. We regret the inconvenience."

Tried different credit cards, same error.  Called support.  They don't know what to do.  They don't know of any issues, but they are not informed of issues.  

Here I sit stuck in this dialog which cannot be cancelled or exited.

Folks, the 3rd TurboTax/Intuit rep resolved this for me.  The problem was NOT with my credit card.  

If you encounter this problem, and if you KNOW it is not a problem with your credit card or address or name not matching, do this:

1)  Close the dialog window for payment.  On windows, you may have to do this from Task Manager since there is no "X" in the dialog window to allow you to close.

2)  Close TurboTax.

3)  Restart TurboTax

4)  Step through the screens to efile, but when you get to the point of indicating you will pay by credit card, click the blue link that says something like "help me do this".  (Sorry, I don't have the screen in front of me.)

5)  A screen will come up telling you how to call TurboTax sales to process your payment.

I had the same problem for year 2020 taxes.   After many attempts (stop/start turbotax, reboot system, remove Ccard from GooglePay, etc) 

I finally got around this problem by logging in as guest in the intuit login page that pops up when getting ready to make the payment.  Do not login with your old intuit account, click on the "login as Guest".  Fill out all the required information (Name, Address, Ccard Number,etc).  This worked for me and I hope this helps you!
