Virginia return with PTET Form VK-1 cannot be filed electronically

[DMN52]

I was surprised to receive the error message that the state return with a VK-1 could not be filed electronically, and that I would have to print and mail the return.  I saw a post indicating that TT had fixed the software issue but I needed to ensure that I had the updated version.  I do and still receive the message. It's pretty frustrating.  Does TT have the capability or not?  TIA for a response.
