Short version: it worked.
I did use the "Estates or trusts" option in federal. I went back in and edited it per your suggestion and yes, indeed, it worked! I got an estate worksheet in the PA section and was able to enter the amount. I then went back to federal and removed the "1" because it cost me a dollar on my federal taxes. 🙂 No change on the state side, and my PA-40 shows the estate income correctly.
