If you are still in whatever business generated the copyrighted content (songwriter, author, artist, etc.) then this is regular schedule C business income like any other income from that activity. You can enter business income without a 1099-MISC.
If you are no longer actively generating copyrighted content for self-employment, then royalties go on schedule E. I'm not sure how to enter them in Turbotax for this year. Presumably there is an interview section for royalties that will allow royalties with or without a 1099-MISC, but I don't know where it is in the program.
(Any legal settlement is taxed according to the character of the income it represents.)
