1099-PATR refund based on interest paid toward land mortgage

I need clarification on whether to report the cash patronage refund shown on 1099-PATR (box 1) as taxable income. This 2023 refund was based on the proportion of interest I paid the prior year for a loan I took out to purchase 50 acres. The land is used for personal enjoyment, but I am also using part of the barn on the land as an office/shop for my part-time job (lawn-care business). Thank you!
