Hi Michelle,
I apologize for the delay in my response.
Based on your example, I agree that a heading is appropriate. However, I recommend using initial capitalization instead of all capitalization. I believe that your example falls under the Note in the rule below.
The answer to your question is found in the Braille Formats 5.2.1a
If the use of small capitals is determined to be a required print font, use a transcriber-defined typeform indicator to indicate the small capitals (Example: HORSE). If the small capitals do not need to be distinguished in some way, the word(s) may be fully capitalized in braille. Note: Use a capital indicator before the first letter of a word printed in small capitals when the initial letter of the word is shown in larger font (Example: HORSE). (In the rules, the H is larger)
