IDENTIFY SOURCE STATE FOR BANK 1099-INT

I am filing for a Grantor Trust established in 2025 and governed by the laws of NJ.  The Grantor's NJ home was sold in 2024 and she was placed in a memory care facility in NJ.  The Trust address is the PA residence of the Trustee/POA.  There is no State indicated on the Bank 1099-INT.  What State is considered the 'Source' of the income?
