Rental Property Depreciation and Business Use Percentage
In 2021, I bought a new home and turned my previous home into a rental property. This is my first time owning rental property, and I am a little confused on how to complete the depreciation section. The box that is confusing me is the "Percentage of time I used this item for this business in 2021:". I am confused as to how this calculation works. The program already asks you what date you started using the property for the business, so is this box asking if it was 100% business use after that date? The box also seems to auto calculate based on start date, but that seems to reduce my depreciation twice. For example:
Full Year depreciation, 100% business use: $6,970
Starting June 1st, 100% business use: $3,939
Starting June 1st, 59% (TurboTax's auto-calculated percentage) business use: $2,324
Which of these entries is correct? The third option seems to be what TurboTax automatically applies, but that seems like it's giving me both a partial value and a partial year. Can someone clarify how this should be filled out? Screenshot of boxes in question attached.
Thanks in advance!
