Can I deduct interest payments I am paying my parents on a unsecured promissory note with a standard interest rate & is lawyer drafted used to purchase a rental property?

For 2018 Taxes.I am repaying my parents on a promissory note I used to purchase a investment rental property. The promissory note is lawyer drafted and has a standard interest rate. The property has never been used for personal use and has been a rental since purchase. If so, how would I do so within Turbotax?
