"the computer crashed"

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 $50, an actual copy of the return.

Contact your state for copies of previous state returns.

If you used online TurboTax:

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

I NEED A COPY OF MY W-2  (or 1099)

TurboTax does not have a copy of your W-2—the Wage & Tax Statement—issued to you by your employer, (nor does TurboTax have copies of your 1099’s).   You should always save those documents for your own records. You could ask the employer(s) for copies or you can get a copy from Social Security (for a fee of $86).

If you saved a pdf of your completed tax return, the worksheets will show the W-2 information you entered, but not the actual W-2.

You can get a wage and income transcript from the IRS:  It will not show the actual W-2, 1099’s, etc, but will show the income information the IRS received.  It will not, however, show your state information. It will only show the federal information.
