Yes same for my client.   Return filed in 2018, did not mark final as cash distributions not completed until 2019 due to court case with beneficiaries.   Did not file 2019 final return as no income, no requirement to file.   Wonder if something in IRS system?   May have client contact IRS to confirm.   Especially since   the LA County made her pay thousands in back property taxes as she was listed as the Trustee.
