Return includes Virginia PTET payment credit not supported for e-filling?

My federal/state returns are ready for filing, and I am receiving this message in TT premier Desktop:

###############################################################

Not Eligible for Electronic Filing, Reason for e-file ineligibility:

The return includes a Pass-Through Entity Elective Tax-Payment credit. Required attachment Schedule VK-1 is not supported for electronic filing.

These rules are set by the Department of Taxation.

The good news is you can still print your Virginia return and file it by mail.

Could you please confirm that I can not e-file and I have to print and mail my return including VK-1 form. I am wondering if e-filing in this situation is just currently not supported and TT is planning to release a new version that will allow e-filing? Or if these kind of state returns that should include VK-1 will always have to be printed and mailed?
