Turbotax Online is free for simple returns. If you require forms or situations not covered in the free return, you will be offered the option to upgrade. If you refuse, you can file your return with another company. When you are ready to checkout and file, you are again shown your fees, and you have the option to stop there, and not pay. Of course, if you don't pay for turbotax, you can't file with Turbotax, and you need to use another provider. (If you walk into a restaurant and refuse to pay, should they serve you?). There are also a number of additional services and benefits with fees, but they are optional.
Normally, paying the fees and filing constitutes agreement to the fees, and Turbotax does not officially offer refunds. You can try calling customer support and see if they will make an exception for you.
