Why would you want to do that? Your preparer should be able to e-file your return, or you can mail the return the preparer gave you.
If you purchase TurboTax to install on your own computer from a CD or download, for Mac or PC, it allows direct entry on the tax forms. However, if you direct enter your entire return, you will not get the TurboTax accuracy guarantee.
Your state may have an e-file online option where you fill out a form online. This would allow you to copy your information from the prepared return to the online return. The IRS does not have this direct option.
