I adjust the cost basis in Box 1e, and there is a question "Was this a sale of employee stock?" I selected "Yes, this is stock that was acquired through an employee stock plan". Then there is a question "What type of employee stock is this?" I chose "Restricted stock units (RSU)." Then I was asked to enter the sale of the RSU and the purchase of stock shares information. I couldn't find the information of vesting (or release) information so I left those boxes blank, and I guess that's where the problem came. I only know the date vested but I don't know where to find total shares vested etc.
