The answer to your "headline" question - "Do I report a 1099" - is YES.
You report any interest income that might show on the 1099-INT section of the form and you report any dividend income that might show on the 1099-DIV section of the form. This gets reported even if you didn't actually receive any cash, i.e., left the cash in Schwab or had the cash automatically reinvested.
You only report realized gains or losses, i.e., where you actually sold a security. Those sales would be reported to you on a 1099-B.
You don't report unrealized gains or losses, i.e., "paper" gains or losses due to the fluctuations of the security prices day to day.
