Why do taxes have to be so damn confusing

I have to file an 1041 form for the estate Im in control of and I tried last night and had no idea what I was doing. So I scheduled an appointment at an H&R block near me assuming they could help. So instead of helping me fill out this bloody form they tell me a whole string on nonsense as if I was supposed to understand it. Apparently I can just take the form I have and go to the bank with it? But it also needs to be done during next years taxes? And there was all this other stuff I need to do unless I don’t need to do them. So now Im back home with no idea what to do and feeling quite annoyed. 😒
