Can I e-file an amended 2023 (state) tax return?

TurboTax says I have to mail in amended 2023 federal return but can e-file amended state (Virginia) return.  But when I try to e-file, I get the following error message:  "Tax Year 2023 transmissions are not available. TurboTax is not ready to process Tax Year 2023 for amended returns."  Does that mean I will be able to e-file my amended state return at a later date?
