I'm donating lots of books to Goodwill. The form is asking for a date required. It won't let me enter VARIOUS for dates that span years. What should I put?

The date that is required is the date of the donation, not the original date that you obtained the books. If you did not receive a receipt for the donation or other personal records, you will have to re-create this information as best as you possibly can.
