Hello,
I've reported this type of royalty from Youtube on Schedule E before, considered in my case as a hobby income, not primary source of income.
I did not enter a physical address in Schedule E.
Under type of property I typed in Royalties for Box A and under Income / Royalties received for Box A I enter the amount I received.
Frankly I don't know why this has to be so complicated, but I feel better that I reported it, even for the measely amount it is. Even if there appear to be different ways of reporting it, not reporting it seems worse, and I can rest easier.
