@Zeek77 what you can do is just convert everything to personal use on the closing date of the sale. That will give you the total depreciation you're required to recapture in reporting the sale.
Then, split your sales data between the two units based on the percentage of the cost basis of the entire structure that was used for depreciation of the rental portion.
Next, report the sale of the rental portion in the Sale of Business property section.
Finally, assuming the unit that was your primary residence was never classified as a rental or any other business use that required you to take depreciation, report the sale of the primary residence portion in the "Sale of Home (Gain or Loss)" section.
