How do I clear out the Earned Income Credit (EIC) section and start again? It told me to try it including/not including Medicaid waiver hardship payments as income.

You can try deleting Form EIC and then revisiting this area. 

If you are using:

• TurboTax Online: see How do I view and delete forms in TurboTax Online?
• TurboTax Desktop:
  1. On the top right, there is a FORMS button.
  2. Click on FORMS.
  3. Locate the form you want to delete.
  4. Click on the form name.
  5. Below the form, bottom left, select DELETE FORM button.
