i selected my medicaid waiver to be counted as income by mistake, now it won't prompt me to change it back in TurboTax. ?? helP?!

I would delete the W2 and then reenter it. 

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.
