You can use the Free Edition but it is for the simplest of returns.If it is asking you to use Deluxe than somewhere along the way you entered information that the Free Edition does not cover but the Deluxe does.You can choose to downgrade but remember you may not get your maximum refund if you do not use Deluxe for the information that your return requires.
To downgrade you can use the Clear and Start Over feature located at the top of the page under My account.This will remove all of your information you currently have input and take you back to choose a product,you will then enter all of your information again.
