Since you are using the desktop product, click on the Forms icon on the upper right. You should see a Schedule Worksheet showing this royalty income with a x=zero. You may also see a 1099-MISC worksheet that is marked as royalty income. If you click on each one to open it, you can then delete it at the bottom of the screen. Do the 1099 first, then the Schedule E Worksheet. If this does not help you, please come back in the comments and tell me why it didn't work so we can think of something else.
