TurboTax does not mail your return for you. You have to print it, sign it, and mail it yourself. When you mail a tax return, you need to sign it on the bottom of the page where it says "Sign Here" and write in the date you signed it by the word "Date". Attach copies of your W-2 and any other documents that show taxes withheld to the left side of the papers where it says "Attach Forms..."
When you print your return, it will print with filing instructions that tell you where to mail it.
It is not required, but is a good idea, to use a mailing service that will track your return or provide you with a receipt showing that the IRS got it--such as Fedex, UPS, or certified mail.
It will take about 4 weeks and then you can track the status of your return at the IRS website. https://www.irs.gov/refunds
Because you have now missed the filing deadlines and you cannot e-file, you need to purchase and download the desktop software to finish and then print your 2016 return. If you did already pay your TurboTax fees you can contact customer support to push a download of the software to your account.
