Business & farm

Thanks so much for your response. I am using the Self-Employed online version. Please forgive me if this is an idiotic question but I'm not sure where to access " forms>Schedule C>"? Interestingly, I just tried deleting the form completely and adding the income under additional income and when I go to file It is throwing the same error code. screenshots below. So basically the entry it's asking me to check no longer exists...
