Sorry you misunderstood. You can never have a tax due deducted from a refund. You will still get the full refund and have to pay the full tax due yourself. Turbo Tax just showed you a screen at the end combining federal and state . But that was only for your own info.
You can only have the Turbo Tax fees deducted from your refund (and only from a federal refund).
If you have the Turbo Tax fees deducted from your federal refund there is an Extra 39.99 Pay with Refund charge.
