First this entry section has been around for a few years and all of the downloaded versions have it however you may need to upgrade to the Deluxe version in the online program. As for the zero income issue for efiling ... simply enter $1 of bank interest to overcome this IRS restriction.
Be aware that the online TurboTax Free Edition is very limited to only simple returns--so be careful----if your return requires any of the schedules or extra forms then an upgrade to a paid version will be required. https://turbotax.intuit.com/personal-taxes/online/
There are still eight various software providers who will participate in the Free File program but they will not be available until sometime in January----so if you want to use one of them---WAIT. Since the IRS will not start accepting returns until late Jan and will not process returns with EIC or ACTC on them until mid February you can afford to be patient especially for free.
