Get your taxes done using TurboTax

I am not sure this is correct. In the 2017 Publication 4681 it states:

Even if you didn't receive a Form
1099-C, you must report canceled debt
as gross income on your tax return unless
one of the exceptions or exclusions described
later applies.

How would I go about reporting forgiven debts if I do not have a 1099-c to go with them? Do I need to call the companies and request a 1099-c? What if they do not have one to give me yet? How would I report that company and the debt forgiven if they have not reported it yet? I am very confused about this. I only have one 1099-c and I should have about 9 of them from debts that were negotiated, paid off and partially forgiven this year.
