After entering a 1099-MISC, TurboTax requires me to select either (1) “Investment income from property you own”; (2) “Royalty income from your business, including artist royalties or operating a natural resources business (Schedule C).” Book royalties would seem to clearly fall under the second choice, but writing just 1 book in my career, over 10yrs ago, would not seem to classify me as “being in business as a self-employed writer” (quoting the IRS guidelines at
https://www.irs.gov/businesses/small-businesses-self-employed/what-is-taxable-and-nontaxable-income). It would seem I need to go the Schedule E route, but Turbo Tax assumes Schedule E is only for rental properties from what I can tell.
