Deductions & credits

I understand that I should be able to include my health insurance premiums, and that of my spouse, since I am self-employed and have only one business. I have been unable  to input the amount of the health insurance premiums. I am not sure why I can not update the business section that includes self employed health insurance premiums. 

Help!  I know that the amount will end up on Schedule 1, Line 17.  Is there a way to override the system and input the information.  I have spent many hours working on this. In the other years that I have used Turbo tax I have been able to input the self employed health insurance premiums. I am getting really frustrated with this since I should be allowed to input the information.

Thank you
