Form 3801 would be populated if you had a loss on your rental activity that was not fully deductible or other passive losses. So it is possible this is the first year you had a loss, that may be why it didn't show up in previous years.
It is a necessary form if you have passive losses from a real estate activity that are not fully deductible.
