How to pay a bonus?

SOLVED

I thought this would be reasonably easy but I am a bit lost on this. How do I pay myself a bonus apart from my regular salary? There appears to be no "bonus" category in the Payroll Cheque form section. Instead, I see Regular, Salary, Overtime, Commission, Income 3, etc. but no bonus. The bonus is not tied to extra hours and is basically just a Christmas bonus.

Any suggestions would be appreciated, thanks.
