I share a Roth IRA account with my husband, we have not made any contributions or withdrawls for a few years now. Do we still need to report anything on our taxes?

We have not received a 1099 form from our Investment firm, if this helps? Not sure if we will even get one.  I know we did gain an increase in value, but it wasn't due to a new contribution, which is why I'm confused as far as reporting it or not.
