Here's a few definitions and clarifications. I'm not wording it exactly like the program does. But you'll see as you work things through, where this clarity is needed and comes into play.
Percentage of your floor space that is exclusive to the renter - This will be less than 100%.
Percentage of time the space was used for business/rental purposes - This is asking that, of the floor space that is exclusive to the renter (less than 100%), what percentage of the time was it used for business DURING THE TIME IT WAS CLASSIFIED AS A RENTAL. This will be ONE HUNDRED PERCENT, provided you did not utilize that space for any personal purposes for one single day DURING THE TIME IT WAS CLASSIFIED AS A RENTAL.
The time before it was converted to rental DOES NOT COUNT for anything. The time after you converted it back to personal use (if you do that) DOES NOT COUNT for anything.
