It means that you elected to print and mail the return, rather than file the return(s) electronically (or e-file).
Your Form W-2 is not stored by TurboTax, you would find any copies of those forms either on your computer or on paper filed with your tax documents. If you did not save your W-2 you can request one from your payroll department. You can review your prior year return for your information that you entered from your 2016 Form W-2.
