I need copies of my tax forms from years 2011-2015, the online options don’t offer those years

They only keep the last 7 years.

The IRS and TurboTax only retain tax returns for the past 7 years.

Tax years 2014 and 2015 should be available from TurboTax if you used the online editions and are signing onto your online account with the exact same User ID and Password you used for the online account.

To access your prior year online tax returns sign onto the TurboTax website with the User ID you used to create the account - https://myturbotax.intuit.com/

Scroll down to the bottom of the screen and on the section Your tax returns & documents click on Show.  Click on the Year and Click on Download/print return (PDF)

If you used the desktop CD/Download editions installed on your computer, the only copy of your tax data file and any PDF's will be on the computer where the return was created.  TurboTax does not store online any returns completed using the desktop editions.
