I filed my 2024 taxes with TurboTax. I now cannot find my 1040 from 2024 because TurboTax doesn't recognize I filed with them, when I have emails to prove otherwise.

Where did my 1040 go? Did TurboTax just permanently delete it then?

  You have to access your own account and/or  print it for yourself using exactly the same account and user ID that you used when you prepared the return.

Start a 2025 return online and enter some personal information  so that the menu on the left opens up and lets you access your past year returns.

Many people have multiple TT accounts and forget how to access them.  Log out of the account you are in now.

Or did you use the desktop version of TurboTax?  If so, the files are on your own hard drive or any backup device you used like a flash drive.

You can get a free transcript from the IRS or for a fee of $30, an actual copy of your tax return.

The emails you received are called notification emails.  They do not have to be the same as the User ID of the account (if the user ID is an email address.)    So it's possible to have a User ID (email address 1), but in the profile settings one can have notification email address 2.   You can have more than 1 account with the same email address for notification purposes (but the User ID's will be different.)

  So if you can't find evidence of the 2024 return in the section "Your Tax Returns & Documents" (which is low down on the Tax Home page) of the account you are now using, then you should look for multiple accounts as @xmasbaby0 mentioned above.
