Hey, @cs45. 

I hope your day is going well so far. In QuickBooks Online, there isn't an option to select "Others." The system is designed to only take Vendors, Customers, Employees, or Contractors. However, I'll send feedback to our Product Developers so they can consider this in one of the upcoming releases. 

You can check out our QuickBooks Blog to see what's new in the product. 

If you have any questions, please don't hesitate to ask. I'm always here to lend a helping hand. Have a great day!
