Copies of your w-2s are not stored with TurboTax. You can view your PDF copy of your tax return to view what W-2 data you entered in TurboTax for your 2021 tax return. Or you can get a Wage & Income transcript to see the details of your w-2. If you need a physical copy of the document and can't locate it, you can purchase copies from the Social Security Administration.
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 $126).

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.
