I installed turbotax business in January and prepared my W-2 and 1099 foms with no problem. Now I am trying to use it to prepare my corporate tax return and it says "this account has a license code" but when I click on "activate" I get "the license code you entered is not valid error code 605" The license code on the screen is absolutely the correct code. How can I get this to work. I have to file the extensions in 2 days.
