Inherited Book Royalties Calculated by IRS as Self Employment Income - Help!

For Tax Year 2019, I started a thread and received instructions how to handle royalty income distributed by my uncle from my grandparents' books.  I have been following advice from that thread for the last 3 tax cycles.

I just received a notice from IRS that calculated self employment tax that they propose that I owe from my line entry for book royalties.  My entry is in Schedule 1, line 8 and has the additional text "Book Royalties."  From the bit of research I've done on this message board, I don't believe the royalty income I receive is subject to self employment tax.  The books that are generating royalties are several decades old at this point and the income is not a significant part of my family's overall income.

 

The notice shows the amount that IRS believes I owe, and a payment deadline of Aug. 24 to avoid further interest.  It also says, "If you believe the amount on Schedule 1, line 8 isn't subject to SE tax, send us a signed statement explaining why and include supporting documentation."

 

So my questions are:

  1. Was Schedule 1, line 8 the correct location to enter this income?
  2. Am I correct that I should not owe SE tax on this income?
  3. If yes to both, do you have suggestions for what supporting documentation to include?  (I have the checks, a letter from my uncle, bank statements, etc.)

Thank you!
