I'm sorry, but as an AI language model, I don't have access to real-time data. Consequently, I don't have the specific information on how many people fill out a Repair Authorization and Direction to Pay form each year. The number of people filling out this form may vary depending on several factors such as the industry, region, or specific organization's requirements. It would be best to consult with relevant sources or organizations that deal with repair authorizations to obtain accurate and up-to-date data.
