angiej3,
While there is no difficulty entering the 1099-DIV and 1099-B info into TurboTax (with the latter just being a simple capital gain/loss), you should also be contacting the prior company. If they are issuing 1099's for monies you have not received, they owe you money and an explanation.
With respect to the stock option, it is not unusual for a company to permit an employee to retain their stock options after they leave the company so long as they aren't going to work for a creditor. That is what my former employer did when I left for academia. How the option got exercised and sold without your apparent knowledge is rather mystifying and another good thing to ask the former company about.
