Why can't I input self-employment income that generated no 1099s?

I have my W2 filed correctly; that's the end, as far as my simultaneous part-time employment is concerned. I also have self-employment freelance income. That income is only a few hundred dollars so I did not receive 1099s. But I want to report that income as Schedule C income. I do not want to report is some vague "other" category that does not generate a Schedule C. I want to report the few hundred dollars I made in 2021 (yes my taxes are late) as self-employment income, even though I did not receive 1099s. I know exactly how much income I made freelance in 2021.

 

I am using the online/web version of TurboTax Self-Employment. Last year it let me report roughly the same amount of freelance income.

 

But now, Turbotax just boasts: 2021 equals $0.00 and when I click "Edit" from "Your 2021 self-employed work summary" under "Income & Expenses" I am taken to "Your [Self-Employment Occupation] Info" where I can adjust my mailing address and so on but not my income.

 

There's nothing wrong with self-employment income and it doesn't require a 1099 to be taxable and go on the Schedule C. 

 

Why is Turbotax trying to force my 2021 income to be $0.00? What do I have to do? It worked last year. What's the deal? This is really upsetting.
