The first year I moved to the US, I had a whole bunch of things going on. Buying a house, working from home, buying a hybrid car etc., getting married. I had no real idea about the tax system, so saved all our receipts etc., and went to H&R Block.
"So what do you want to claim?"
"What can I claim?"
"What do you mean?"
"Here's a bunch of receipts and I can tell you all the details."
[vaguely confused look] "Let's go through the app."
And I watched as basically she transcribed our most basic information into their in house version of something akin to TurboTax.
I could have done that myself.
I complained. And did, eventually, get someone there who knew how to not be a glorified transcriptionist.
And then the next year found someone who had knowledge of their own.
It hit a weird case and she didn't know what to do. Eventually I looked up the actual tax code and told her what to do. As far as I remember it was about splitting the cost basis over multiple years. I owned some weird stock where that came up.
My tax preparer is something like $250 a year and reduced my liability in a very tumultuous year from about $20K to about $9K by understanding what I actually had going on and helping to work through it.
