Qualified business income on Schedule C: what is it? I have an honorarium that I entered and I have no expenses. TT is asking if "Qual business inc - yes or no".

I received an honorarium in 2018 and got a 1099-MISC.  When I entered the amount under section '1099-MISC and other income'.  TT has it under the 'Business Income' section and asked questions about Schedule C, including Qualified business income.
