If there is a PTET credit, then Virginia requires a VK-1 to be attached to the return. Since this error is specifically due to TurboTax not including the form with the e-file transmittal, you have no choice but to print on paper and send the return in. I did this last year and although it takes longer to process and is not ideal, just consider it a throwback to an earlier time. Bummer that this is still a thing. Someone at TT should read this and fix it.
