Hey, first of all, don't worry. You'll still be able to get your tax refund, if you are due one. If you are due a Federal refund, there is no penalty for filing late.
What is the rest of your story? Did you choose to file your return by mail, i.e., by printing and mailing? If so, then yes, you would have to print it, sign it, and mail it yourself. TurboTax does not print and mail a paper return for you. Do you still want to file by that method? It can take the IRS about 6 weeks or longer to process a paper return.
Or do you want to switch filing methods and try to efile? If so, see this FAQ. It tells you how to open your return back up, change filing methods, and go on to efile. NOTE: If you have already actually filed (e.g, actually printed and physically mailed the return), don't file again.
