When entering a 1099-B, I'm being asked "how did you receive this investment?", but none of the choices provided match my situation (RSU from employer). What can I enter?

Turbotax doesn't give me the option of "other" and won't let me proceed without answering, but none of the options match my situation (purchased, inherited, divorce, gift, short sale, demutualization / life insurance). These were restricted shares of my company that were given to me as incentive compensation.
