I'm a club advisor of a high school and a Cal State University pays me for doing that. I got a 1099 MISC from it. What's the principal business code should I use?

Based on your question, I'd suggest "611000" for "Educational services (including schools, colleges, & universities)."

Sometimes the codes aren't specific enough for certain occupations, and you just have to go with what's closest.

Please see "Principal Business or Professional Activity Codes" in the IRS' Instructions for Schedule C if you'd like to search for a more appropriate code.
