Can you explain to me why I don't have a tax form for my wealth accumulation account?

Basically mom’s using TurboTax for the tax return because the guy we always went to kept making bad mistakes, so dad figured we just do it ourselves.

I started doing this wealth accumulation thing with a friend last year.

So when my mom asked if I had a tax form from that I said no. But dad is all flipping out and saying that doesn’t make sense. I ask my friend but I am as versed in finance as I am in Egyptian hieroglyphics. My friend said this in verbatim “You didn’t take any distributions and all your contributions are already post tax so there is no tax form. So in short no tax form and nothing to worry about.”

So. . .

that means. . . ?
