why are you charging me when you said it was free

We cannot see what version of the software you are using.   Did you "start for free" using online?   If you entered something that went beyond a "simple" tax return then you upgraded to a paid version and the screens did alert you to it.   

WHY DO I HAVE TO PAY?  I WANT THE FREE EDITION

The information that you can enter in Free Edition is pretty limited now.  Thanks to the new tax laws that began for 2018 returns, there are no more simple Form 1040EZ or 1040A's.  Everything goes on a Form 1040 that has three extra "schedules" with it, and if you need any of those schedules, you are not able to use the Free Edition.  Using the standard deduction instead of itemizing does NOT mean you will not need any of those schedules.https://ttlc.intuit.com/questions/4511011-what-happened-to-the-1040a-and-1040ez   If you started in the Free Edition and entered any data that required any of those three schedules, you have to upgrade to a paid version and if you are watching the screens carefully you are alerted to the upgrade.

When you chose to “start”  in the Free Edition —

Directly below the words “Free Edition” there is a blue link that says “For simple tax returns only”   If you click that link it brings up this information:
