I don't think there is anything you can do to avoid it in connection with the rental.  If you go to the "Earned Income Credit Worksheet", you can manually enter the rental income (profit) on Line G of the Smart Worksheet between Lines 7 and 8.

As you can see from Line D of that worksheet, Intuit interprets "rents" as from non-real estate, and does not consider non-passive real estate to be "rents".

However, be aware that the "investment income" limit is dramatically increased for 2021 ($10,000?).
