TurboTax has no copy of your W-2's, but you can look at the wage worksheets to see what wage income figures you entered for each of you into the program.
Here's how to open your return back up to go the Print Center where you can choose various PDFs.
NOTE: When you open your return back up, do not make any changes in it if it's already been filed.
NOTE: Do NOT use this method to open a return to make changes/edits to an already-filed return (one that has actually been mailed or efiled.) If you later need to make changes to an already-filed return, you have to go through the formal amending process, and your return must start off exactly as originally filed.
NOTE: Remember all PDF tax documents and tax data files are very sensitive files, since they contain your personal ID info, financial data, and possibly bank account numbers, etc. Be sure to store them safely and securely to guard against computer theft, hacking, etc.
Super DoninGA has left you some additional info in his comment below.
TurboTax does not have a copy of the W-2 or Form 1099. It would have W-2 and Form 1099 worksheets that included the tax data from the forms that were entered. The worksheets would be included in the PDF of the tax return in the tax year the return was completed.
Copies of a Form 1099 would have to obtained from the issuer of the form.
