How do I classify settlement and royalties, Schedule C or Other Income?

I'm a writer. A publisher paid me a settlement for infringing my work. They also paid me retroactive royalties on the work (what I would have earned had I licensed the work to them legally). I allowed them to continue selling the work, and they have been paying me current royalties as they were earned. I assume that all the royalties (retroactive and current) will be reported on Schedule C. But should I report the settlement portion of their payment on 1040, "Other income"? Thanks.
