It's the 1099 / Schedule C loop from hell; Nothing is working to link.

I've used Turbo Tax for years with no problem. I've used 1099s in the past, no problem. This year, after entering 1099 and expenses, when i go to file, Turbo Tax brings up a "Schedule C worksheet" and asks for a link. WHAT LINK? Everything in the help section claims that if I fill in 1099-NEC, turbo tax will "AUTOMATICALLY FILL OUT THE SCHEDULE C" so what is happening? This is exhaustive and keeps asking me to upgrade and pay more for answers. However, this seems like a problem with the Turbo Tax program versus user error. I'm doing everything it asks. HELP.
