Converted a 100% rental to 50% rental/ 50% personal use

In 2021, I moved into my rental property, which I had rented 100% and depreciated on previous year’s taxes. As of April 2021, I now occupy 50% of the property as my primary residence. How do I effectively end the 100% rental period and then divide between 50% personal use and continue to depreciate the other 50% I am still renting in Turbotax and report the rental income? @Carl 

 

I have made no major additions or improvements in the last couple of years when I was renting the property. How do I determine the new basis for the structure for the current period of 50% / 50% use starting April 2021? Do I need to refer to the old basis amount with depreciation?
