If it really bothers you, contact Media Services, do not mention that you should have gotten a W-2 as they are foreign royalties and will come on a 1099-Misc. Once you have that form then follow your supposition to report it as 1099 income and do a Schedule C since you didn't want to take on the advice multiple experts have weighed in during this conversation over 4 to 5 years!
Otherwise, legally you can actually do a or b. Consider that you don't have any other self-employment income, why would you go through the whole schedule C, BS, unless you have other significant foreign royalty income where you want to take business deductions, especially since the Trump tax changes stopped actors from being able to use deductions with their W-2 income!
As long as you legally report it, you can do either way as I described above and linked to the previous person's answer. I've been doing actor taxes since I returned to the US in 2001 & I use TurboTax premier. Even they have me down as zero red flags and, it's all legal.
I've been looking in on this question & answers in different locations on the web for years. There is no other answer that anyone else's given. Period. Stop. The End, Yay!
