The Screen of importance that I'm referring to is titled "Was this property rented for all of 2018?" I assume you are selecting NO.
The small print near the middle states: During the period in 2018 this property was a rental tell us how many days this property was rented at a fair rental price and used for personal reasons. Don't include days when the property was vacant.
Now lets say you converted the room or space to exclusive rental use on Nov 1, 2018 and from that date forward you never used that room or space for your personal use. Then you got it rented out and a renter moved in on Nov 5 2018,
Your days of personal use is "ZERO". Your days rented is 55. Prior to Nov 1, 2018 the property, space or room was *not* a rental. So you don't count the days before Nov 1, 2018 for anything.
