What tax year? TurboTax does not have a copy of your W-2. Only you, the issuer and the Social Security Administration have a copy of your W-2 as issued to you by the employer that issued it.
If this is needed for FAFSA, you don't need the W-2. Get the transcript of your tax return for up to 3 years back directly from the IRS for free at <a rel="nofollow" target="_blank" href="http://www.irs.gov/individuals/get-transcript">http://www.irs.gov/individuals/get-transcript</a>
If you don't have it, and can't get it from the employer that issued it, then you MIGHT be able to get it from the social security administration. <a rel="nofollow" target="_blank" href="https://www.irs.gov/taxtopics/tc159">https://www.irs.gov/taxtopics/tc159</a>
I NEED A COPY OF MY W-2
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.
