THANK YOU VERY MUCH. The silence was deafening and I have been checking every day for some information someplace. I've never tried the pay-through-app process before and was also confused by the message on the payment dialog. It looks like you posted the on-line dialog - I have not found a way to get back to the "pay taxes" dialog in the desktop version, so I couldn't confirm that there were additional steps necessary.
The "Electronic Filing Instructions" are contradictory (always check your tenses when writing - pay vs paid here):
Balance | You've chosen to pay for your state balance due of $XXXX.XX by
Due/ | credit card. Double-check your credit card statement to make sure
Refund | your payment was received by Virginia. This will help you avoid any
| possible interest and/or penalties. And since you paid by credit
| card, you don't need to mail a payment to the state.
How to Pay | Make your payment by visiting
Electronically | https://www.tax.virginia.gov/individual-income-tax-payment-options.
