This answer is not correct for TurboTax for Business 2019, which is what the question referred to. Selecting "Less Common Income" does not lead to anything marked "miscellaneous income" or any way to get to a 1099-C form.
The Help feature tells you to search for "1099-C" and then select the "Jump to" link, but TTB unlike TT for individuals does not offer a "Jump to" link.
This is a flaw that TurboTax should fix.
