TurboTax cannot mail or email your tax returns to you. You can download a PDF of your tax returns and print them yourself. If you do not have a printer then save the PDF to removable media and take it to a friend, relative, library or office supply store to print.
Why cannot you e-file the tax return?
See this TurboTax support FAQ for changing from mail to e-file - https://ttlc.intuit.com/community/e-file/help/how-do-i-change-from-mail-to-e-file-in-turbotax-online...
