After you file

Did you file a 2023 tax return on 4/9/2025? Did you mail the 2023 return. It can not be E-filed. Did you use 2024 tax software to file the 2023 tax return? I filed 2023 tax return around 3/15/2024 using turbotax 2023 version. And got email saying IRS accepted the return. Recently, when trying to put in AGI when efiling using turbotax 2024 for 2024 tax return, IRS keeps rejecting, as the AGI was wrong. So, I logged into IRS website and found verification of 2023 non-filing letter, this means my 2023 tax return still not processed?
