Why am i being charged this year to prepare taxes?

You should review your fees in your TurboTax account to find out what type of fee you are being charged. Sometimes you start with the Free Edition (which is typically a simple form 1040), but as you enter more complex forms or sections you might be required to upgrade depending on your individual situation.

Why am I being charged for TurboTax Free Edition?

Because you are using the Deluxe version which is not free. If you started the Free version then your taxes included something that the Free version could not handle and required an upgrade to the paid version. You should have been notified of this at the time of the upgrade but did not realise it.
