Deductions & credits

I have been using turbotax for 20 years, and I am a financial (not tax) accountant by trade. So I do feel as though have experience and knowledge and this is not letting me do what I need to do. 
there is no option to “add expenses “ 

i am itemizing because I have my own business and many expenses. 
I have tried to search for the schedule but it brings me right back to the message. 

sounds like it’s a problem if others are experiencing it as well. 
i have over the % for medical and how would turbo tax know what my medical expenses are when I have not entered them
