Deductions & credits

I only purchase mutual funds in my HSA and I don't sell the funds (and i live in California).

Do i still need to report earning e.g. interests and dividend from HSA each year if i don't sell them within the year?   I thought HSA is like a retirement account therefore report of earning can be deferred, i.e.  only report when funds are sold ... , please correct me if wrong.  Thanks.
