Free Edition is for simple filers that file a 1040EZ (or a 1040A with a standard deduction).
The 1040EZ is a one page return for Single and Joint Filers with No Dependents. The 1040A includes more income and deduction items and allows for Dependent exemptions.
Schedule A and additional benefits are provided with Deluxe, our most popular version. So if you have enough deductions to itemize, that may be why you are seeing a lower refund.
Hope this helps!
