IP royalties
I've never been self employed. I've been retired for 4 years. Every year I get a couple of royalty checks from my longtime employer for my share of income for licensed IP that I contributed to developing. This year when doing my taxes on TurboTax, the instructions led me to paying self-employment tax on this income, which doesn't seem right! I'm not working, I'm just getting paid for something I did in the past. Did TurboTax steer me wrong? Did I make a mistake in how I declared this income? How should it be reported?
