That is correct. Date sold "various" is not an option. If you sold a security on multiple dates, then enter each sale separately with its own date.
We use the dates you bought and sold the items to figure out your holding period (how long you owned them). There are different tax rates for a short-term period (one year or less) and a long-term period (more than one year).
