Investors & landlords

My RSU's got vested and the employer withheld taxes on them. However, I did not sell any of the stock units during the entire year. My Brokerage did not provide me 1099-B saying that there is no sale, I am not sure if that is correct since my employer already withheld taxes (stocks) and I have remaining shares.

Is the brokerage supposed to provide me 1099-B in this case ?
