Attempting to provide guidance in a forum such as this, in which the end result is based on facts and circumstances, is difficult.
However, based on your limited facts, in which you indicate the rental activity did not rise to the level of a trade or business even with the safe harbor, then there are no QBI losses available for this activity.
As such, those should all be removed.
*A reminder that posts in a forum such as this do not constitute tax advice.
Also keep in mind the date of replies, as tax law changes.
