How do I download an Old W-2 that says it’s unable to download?

You cannot download an old W-2 from TurboTax.    TT does not have copies or images of your W-2's.   Only the data that was entered when you prepared the tax return is on the worksheets;  TurboTax does not ever have copies of your W-2's   If you need a copy for some reason, ask the employer, or seek one from the IRS for a fee of $30.

I NEED A COPY OF MY W-2  (or 1099)

 W-2's come from employers.  There is not a federal or national website that provides W-2’s.  

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 $62).

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.

Or you can pay the IRS $30 for an actual copy of your tax return which will include copies of your W-2’s
