Yes, that seems to be exactly what is happening to me... I attempted to e-file my federal return, MO state return, and Kansas City RD-109 for Taxpayer return and received the "Success!" checkmark followed by "Tax Year 2024 transmissions are not available." Using the link provided in the TurboTax Help TurboTax Link , I found out that the Kansas City RD-109 won't be available for e-file until 2025-02-27 (today is February 16).
So I will put it in my calendar, and try again after February 27!
