Can I file a 23 and 24 return at the same time?

Trying to file for my son who has one job and is a full time student. He did not file 2023 and it is now time for 2024. Can i file both at the same time?

No, you cannot enter 2023 tax data on a 2024 tax return.  The TurboTax online editions are Only for tax year 2024

To complete and file a 2023 tax return using TurboTax you would need to purchase, download and install on a personal computer one of the 2023 desktop editions from this website - https://turbotax.intuit.com/personal-taxes/past-years-products/

A 2023 tax return can only be printed and mailed, it cannot be e-filed using TurboTax.
