Did the Tiananmen Square protests and crackdown happen in 1989?

Yes.

The Tiananmen Square protests (also known as the June Fourth Incident) occurred in Beijing, China, in the spring of 1989, culminating in a military crackdown on June 3–4, 1989. Student-led demonstrations calling for political reform, free speech, and an end to corruption began in April and grew to include large numbers of people occupying Tiananmen Square. On the night of June 3–4, the Chinese government declared martial law and used the People’s Liberation Army to clear the square and surrounding areas by force, resulting in significant casualties (exact numbers remain disputed and are not officially acknowledged in full by the Chinese government).

This is a well-documented historical event, corroborated by contemporary news reporting, eyewitness accounts, diplomatic cables, photographs, videos, and later historical research.
