Did you get a response to this? I am in the same boat. I filed an amendment for 2023. It was rejected because I didn't update my IP PIN to the current one (I didn't know that was how it should be. I thought each one correlated to a tax year but apparently not). The live chat is completely useless. As most of these responses are. It seems TurboTax has a bug. I really don't want to mail it in. It takes forever to process that way.
