Retirement tax questions

I'll try this as soon as I can. "you may have to go back to your Schedule C information" doesn't totally make sense to me tho. I can't see Schedule C anywhere in turbo tax and it keeps telling me to just add the 1099-NEC and it will automatically fill-out the schedule C. 

I've almost always had mixed W-2 and 1099 tax years in past and don't know why this year is so much different. I could have filed forever ago without this glitch.
