I was in the same position when I had rental properties and I filled out the Form 8582 when I had a net loss but not when I had a net gain.
You'll see why on Page 3 of the Form 8582 instructions - Special Allowance for Rental Real Estate Activities.

So, yes, under that rule, you do actively participate and you really don't have to be concerned with anything until you have $25,000 in losses to deduct and/or your income reaches $100,000.
Here's the form:

However, based on the Exception on Page 1, it looks like you don't have to fill out the form 8582.
Leave it to the IRS to write something like this. LOL.
"Rental real estate activities with
active participation were your only
passive activities."
