Did you get a Federal Form 1040-X in your printed return? If not, it sounds like your Federal amendment was not completed in the TurboTax program. You said you entered your new data, and all the forms looked correct; then you manually filled out the 1040X and CA540X and mailed them.
Since we can't see your return in this forum, it's hard to say what happened. It could be that the Filing Instructions page is wrong, if your printed copy contains a correct 1040X. If it does not, you could Amend just your Federal return again so it generates a correct 1040X for you. Then save your amended returns to transfer into 2025. If you're using TurboTax Online, clear your Cache and Cookies first.
If you're using TurboTax Desktop, were you able to drill down to the unrecognized amount on your initial 1040X to locate the source? Did your income amount in Column A, Line 1 change from your original filed return? If so, you can enter the correct amount directly on Form 1040X. I couldn't recreate your scenario in my test return, but my best guess is that an update changed something in your original return.
We can take a closer look at this if you are willing to send us a 'sanitized' copy of your tax file, with the original 1040 and the 1040X with the error. All personal info is removed. If you're using TurboTax Desktop, choose 'Online' at the top, and 'Send Tax File to Agent'. In TurboTax Online, in the left-side menu, choose Tax Tools > Tools, then 'Share my file with agent' from the pop-up menu. Post the Token Number you're given here (a screenshot).
