If you can post a question here, you can use TurboTax Online.
An internet connection is required to use TurboTax.
If there is some reason that you cannot use TurboTax on the same internet connection that you used to ask your question, either go somewhere where you can get an internet connection, go to a local tax professional, or go to a VITA or TCE site where they will prepare and file your tax return for free.
