How do I know if a company filed a 1099 - c against us for debt settlement?

Ask them .... they could take years to file one.

They would either send you one or you can check your IRS transcript (they would have had to send one to them as well):

You can check your IRS transcript directly thorugh their site at: https://www.irs.gov/individuals/get-transcript
