@pschnoor9 You need to get a corrected form 1099-MISC and have the income entered in box 3. The instructions for box 6 state -
Enter payments of $600 or more made in the course of your trade or business to each physician or other supplier or provider of medical or health care services. Include payments made by medical and health care insurers under health, accident, and sickness insurance programs. If payment is made to a corporation, list the corporation as the recipient rather than the individual providing the services.
None of that explanation for box 6 applies to someone who earned income based on a clinical trial. If the payer will not change the 1099-MISC, then you report the income as other income reported in box 3.
