I think the problem is that it’s just easier to explain what to do for someone having a problem by telling them to paste a line of text into the terminal. Having to walk a user through gui navigation is a pain.
That means, though, that anyone getting help to get gud at Linux is going to mostly be leaning terminal commands.
You can always just transfer it yourself. Withdraw it from a physical location (assuming there is one) for that bank and deposit it in your own hsa account.
