Here's a rough version of the scenario:

Client owns vacation/rental property in NC. 

In 2023, property rented 150 days, used 10 days personal use, so less than 10%. 

In ProSeries, the Sched E worksheet properly splits up the mortgage interest & property taxes into business vs personal use. 

But only the property tax piece is carried over to Sched A, not the mortgage interest piece. 

So my question ... is this just a ProSeries blip? Or is there a reason the mortgage interest piece does not belong on Sched A?
