Here is a suggestion from DMarkM1, and RobertB4444 that has worked for other customers in your situation.
DMarkM1 says "In your online version enter a fictitious business that you will delete later. Just enter some simple basic information and then only some minor income and no expenses. Once done go back into the IL interview to see if the business section is now visible. Make all your entries there for your credit. Then go back and delete the business from your federal interview."
