A property that is rented for less than one year, where the start/end dates do not cross tax years, does not have to be depreciated. So you should be fine for the 33% rental period. But you need to confirm beyond a doubt that no depreciation for it is showing on your 2021 tax return for the period it was 33% rental.
I assume you entered it on SCH E. If so, please take a look in the assets/depreciation section and if the property is listed there, elected to edit it and work it through. Let me know if it shows any depreciation, regardless of how small. We'll go from there.
