I was trying to efile a 1040X for 2024 and the state return was automatically amended. When trying to transmit them both (federal and state) I was receiving a transmission error. When I realized that my state may not allow electronic submissions for amended forms, I opted to print the state forms and efile the federal (1040X). When this change was made, the federal amendment (1040X for 2024) transmitted successfully, and a follow-up email from TurboTax was received stating an email will be sent in 24-48 hours letting me know if the return has been accepted.
