Yes, it it too late to Efile an Amended Return for 2023. You'll have to mail it.
Start Amending in your Federal return by making any changes there (even if you're not Amending it), so that the info flows into your Virginia return.
It sounds like you added a Deduction or Credit, if your original return showed Tax Due, but your Amendment shows a Refund. You'll need to enter an short explanation of what you changed ('Added Child Tax Credit, which was not on original return', for example) for your Form 1040X.
If TurboTax tells you it doesn't see a difference in your Amended Return, look at your Form 1040X. Your change amount will show in Column B, with Original Amount in Column A, and Correct Amount in Column C.
If your Amendment now shows a Refund, continue through your State interview and then you can View/Print/Save your 1040X to be sure it is correct before you file it.
Here's How to Undo an Amendment if you want to start over.
