State FML is treated the same as Unemployment, and both are in Box 1.

"Box 1. Unemployment Compensation

Enter payments of $10 or more in unemployment compensation, including Railroad Retirement Board payments for unemployment. If you make payments from a contributory program that has been deemed to be in the nature of unemployment compensation, such as California's Family Temporary Disability Insurance payments or governmental paid family leave program payments, file a separate Form 1099-G for payments from each contributory program. Enter the total amount before any income tax was withheld. If you withhold federal income tax at the request of the recipient, enter it in box 4; see the instructions below."
