How do I file back taxes from last year and the year before?

To file your tax returns for prior years, please follow the instructions in this TurboTax Help article.

To complete and file a prior year tax return (2022 thru 2024) using TurboTax you would need to purchase, download and install on a personal computer one of the desktop editions for each tax year required from this website - https://turbotax.intuit.com/personal-taxes/past-years-products/

A prior year tax return can only be printed and mailed, it cannot be e-filed using TurboTax.  Use a separate envelope for each tax year being mailed.
