I need copies of my returns that were lost on my computer from 2014 and filed with turbo tax, is it possible to get from turbo tax

TurboTax  online and the IRS save returns for seven years and then they are gone.    Returns prepared using desktop download software were only stored on your own hard drive; they are not stored online.

  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 2024 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.

Account Recovery

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.

SAVE YOUR TAX RETURNS !

EVERY year before mid-October you should save a copy of your tax return as a pdf and print a copy of it for your records.  That way you will not be searching online frantically when you need it for a lender, FAFSA forms, your next tax return, etc.

NOTE:  TurboTax and the IRS save returns for seven years.  Returns older than seven years are purged.

If you used desktop software downloaded/installed from a CD to your own computer, then the tax files are stored locally on your own hard drive or any backup device you used like a flash drive.  They are not stored online.  If you cannot recover them due to a hard drive failure, etc. you can get a free transcript from the IRS or for a fee of $30 an actual copy of your tax return.

if you used desktop those files would only be on the computer where you prepared them. if the drive is no longer accessible, they're gone for good. if you used online Turbotax probably deleted the files older than 7 years.
