How do I clear my entered information?

As long as you haven't submitted payment, deducted the TurboTax fee from your refund, or registered your product, you can erase your return and start from scratch in TurboTax Online. If you have done any of these things, you'll need to manually edit your return.

That worked for the most part, but it still would not allow me to modify the dependent care section. I found that waiting about 30 days (after clicking that button) allowed me to basically start "fresh".
