In the Business Expense section, and subtopic "other common expenses," when you click "Meals" even though it says traveling, the next screen has the 50% and 100% choices, and has a example of each. When you click on 50% or 100%, it has even more examples.
If you need a list of navigation steps to get to that section, let me know as well as which of the CD editions you are using, but it sounds like you already know how to get there but didn't click on Meals and proceed.
By the way, the answer in this thread is for the threadowner who is using Online Self-Employed Edition. The screens in the CD version may be titled differently.
