I need to mail my taxes to the IRS, how can i print it and send it to them if i already chose the electronic route?

Yes you can change from e-filing your federal return in Turbotax Online to mailing it in - please see the following TurboTax FAQ, "How do I switch from "E-File" to "File by Mail" in TurboTax Online?":
