You cannot use TurboTax's Free Edition if you have self-employment income. only very simple Form 1040 returns with no extra forms or schedules can be filed using the Free Edition. You need to use online Premium or any version of the desktop download software in order to prepare a Schedule C for your business expenses.

This is a user community forum for the regular TurboTax products (non-bundled), and it's not clear what you mean by "bundle." So we have to guess a bit.
Are you by any chance referring to a QuickBooks Self-Employed bundle that includes TurboTax? If so, then see if this answer by a QuickBooks employee at QuickBooks is helpful. While your situation may not be the same as the user's question there, the article at least tells you the method to contact QuickBooks Support to speak to someone there, if necessary, by phone or chat.
Folks in this TurboTax forum are not as likely to be able to help with QuickBook products. If that's your product, QuickBooks also has a community forum at the following page where there is a green
"Ask the Community"
button:https://quickbooks.intuit.com/learn-support/us-quickbooks-community/misc/03/community-us
If that's what you have, then QuickBooks should be your main source of help for how to access TurboTax correctly, but should you, however, also need to speak to TurboTax Support at any point:
FAQ: What is the TurboTax phone number?

If you're using QuickBooks Self-Employed bundle, I also found another article and video at QuickBooks support site on how to export your QuickBooks tax info into TurboTax. I assume that's how TurboTax knows not to charge you--as long as you are using the same account. But again, as I mentioned above, this community forum at TurboTax is unlikely to provide much help in regard to QuickBooks. You can phone or chat with QuickBooks Support.
