As of January 5, 2024, the IRS is now open to e-file amended 2022 returns, as stated here:

California also accepts online (e-filing) amended 2022 returns, as stated here:

However TurboTax did not succeed in doing this. I ran into these problems. After transmitting the returns, it gave me an error message because I had entered a date in January 2024 as the signature date. It required a signature date during calendar year 2023. Of course this is ridiculous. I called support and they suggested putting in 12/31/23, which I did, and transmitted the returns again. I ended up in an inconsistent state where I got a screen confirming that the amended returns were accepted, but also got error message indicating they weren't. I have not received any confirmation emails, so I assume they did not go thru. Not sure what to do.
