How to enter 1099-Misc Box 7 Income when it is from "Sporatic Activity"

I have a single, low value 1099-MISC, from a business to myself, with the reported value in box 7.  The funds are from genuinely sporadic and " outside of my mainline skills" work, so how do I best report it under other income?  Particularly, what type of description is the IRS looking for in this case for "List type and amount"?
