Dad passed away in 2021

The estate (trust) received rent payments for 2022, this is the way he phrased what he has.

The client has his own job and has a w2 to file.

The way he explained the situation is that he has multiple siblings but he is the one who is in charge of the estate. I set up an appointment on Sunday to go over his options. But all he said was that it was an estate trust :(. I asked him more questions but he seemed a little lost. I have read a few articles but since his answers were not clear, I'm not sure where to start.
