TurboTax doesn't have your W-2. You will have to contact the employer that you had in 2023 to request a duplicate copy.
If you don't have success getting your W-2 from your employer, you can request Wage & Income Transcripts from the IRS. For more information, refer to the TurboTax article What is an IRS Tax Transcript and How Do I Request One?
Refer to the IRS article for instructions Get a tax transcript online.
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.
