Investors & landlords

Hi, this was my primary residence. I turned it to long term rental since 2020 (100% used for rental since then). When I first added the house, I put in the date when it was placed into service and % used for business. I thought during that year I used the house for personal use prior to using it for rental so the % for business use is equal to months of renting/12 months. Was it correct ?
