Your fee is not based on the amount of your refund or even whether you are getting a refund---your fee is based on the version of the software you used. You could owe a software fee even if you get no refund and owe the IRS, too.
If you have not registered, paid or e-filed you can clear and start over in a lower version of the software.
If you started in the Free Edition and entered any data that required any extra forms or schedules, you have to upgrade to a paid version and if you are watching the screens carefully you are alerted to the upgrade.
