If you have already e-filed your tax return then please log into your TurboTax account and once you log in the first screen that comes up you should see "track my refund" right under that is "download/print return".
If you haven't yet paid for TurboTax (or registered, if you're in a free version), you'll need to do so before you can print.
If you have not e-filed your return yet then please follow the steps below to print your tax return:
Sign in and open (continue) your online return, if you're not already signed in.
From the My Account drop-down at the top, select Print center.
In the TurboTax Print Center pop-up window, click the first option (Print, save, or preview this year's return) and follow the on-screen instructions.
