What, exactly, is free? Not only am I paying to file federal, paying to file state, but I'm also paying a HEFTY processing fee!

If you have the Extra $40 Refund Processing Service charge (45 in California) you can avoid it by paying the Turbo Tax fees upfront with a credit card.  Remove Pay with Refund fee

To go back to a lower version or the Free Edition you can try to clear and start over https://ttlc.intuit.com/community/using-turbotax/help/how-do-i-clear-and-start-over-in-turbotax-online/00/26444

If you started your tax return in TurboTax Free Edition (Form 1040 with limited credits; roughly 37% of taxpayers qualify), you won't need to clear and start over. You can select Switch to Free Edition instead.

In the Turbo Tax Free Edition, information that you can enter is limited now.  Why do I have to upgrade from the Free Edition?

Or try the IRS Free File program

TurboTax Free Edition is free. The tag below your question says that you are using TurboTax Live Basic Online. That is not free.
