FILING 1041 FOR IRREVOCABLE TRUST USING TRUST EIN

Hello, I am doing a relative's taxes. She has dementia and is in a memory care facility. I have already filed her Federal and PA returns. She also established a "Grantor Trust" "Irrevocable Trust Agreement" last year. My Wife is POA and Trustee (I am Successor Trustee). The Trust has an assigned EIN. The Asset Holder, a Bank, issued the Trust 1099-INTs to the Recipient's TIN = Trust EIN.
My understanding is that I need to additionally buy TT Business and file a 1041 U.S. Income Tax Return for Estates and Trusts, using the Trust EIN, reporting the 1099-INTs and Interest, and pay any taxes owed from the Trust accounts. Is that correct?
Also, for PA, do I file the PA-41 and is that also only accessed through TT Business?
Thank you.
