I used turbo tax self employed edition that charges how do i use the free edition that is no charge to file I believe without entering all my information again?

Unfortunately, once you have upgraded or added features to your TurboTax return, there is no way to downgrade or remove the extra features. You would need to create a new return to go back to the original product. 

Simple tax returns can be filed for free. To learn more about what's included in a simple return, please follow the link: Simple tax returns. 

Thank you for choosing TurboTax.
