Turbo Tax doesn't have copies of your W2.  Only the info you entered from it or imported.  It would have W-2 worksheets that included the tax data from the forms that were entered.  The worksheets would be included in the PDF of the tax return.

See,  https://ttlc.intuit.com/community/forms/help/how-can-i-get-a-copy-of-my-w-2/00/26328

You can download the pdf file with all the worksheets and see a summary of what you entered.
