I do not think this applies to 2020 and beyond.  Same question, how can I e-file Virginia?

Help with correctly amending your return has been provided by clicking here.

I have followed your link’s procedure exactly and it skips the state submission entirely.  Virginia allows E-filing of amended tax forms.  The software only files federal.   I was told to wait for a software update.  Is this correct?

Please contact TurboTax customer care. Assistance with doing so has been provided by clicking here.

Additionally, you can file your amended federal.  

Here are two links that will tell you the TurboTax Expected Availability dates for 1) Federal forms

TurboTax Expected Availability Dates for Federal Forms

and 2) State forms:

TurboTax Expected Availability of State Forms

The Virginia amended return is filed on Form 760, the same as the regular return.

The federal 1040X is now available.  You may need to update your software.

Thank you.  However, my amended Virginia return does not include any unsupported forms within the list.  When I try to e-file my TurboTax software on Mac only lets me file federal and skips over the state amended return.   I have updated my software to the latest.  I have had a rep share my screen and it will not e-file or give an option to a Virginia State amended form.   Please help.

You will need to print and mail your amended state return because e-filing is not available for your state's amended returns.

Can I e-file my amended state return?

Here are instructions to print and mail your return.

How do I print and mail my return in TurboTax Online...

If submitting amended return Turbotax will e-file Federal but skips over Virginia e-file process.  Can you please confirm it has to be printed and mailed.  

You should be able to Efile your Virginia Amended Return.  Since we can't see your return in this forum, I would suggest you step through your Virginia amended return again.
