I wrote a book 15 years ago and had been reporting royalties on schedule C. I am now retired. Do I now report my royalties on schedule E since I no longer write?

I had still been attempting to write until this year but have had nothing published. I am no longer writing at all but still receiving meager royalties.  I have found conflicting answers on Turbo Tax support.  I have attached the one that seems appropriate for my situation But I have also read posts that state that all royalties for having written a book in the past should be reported on schedule C. Thank you in advance for your help.
