The winner will serve the last two years of Courson's term.
Courson resigned June 4 after pleading guilty to misconduct in office in the State House corruption probe, triggering the special election.
Filing for the seat ended Saturday at noon.
District 20 stretches from the southern neighborhoods of Columbia to the northwest, along Interstate 26 into portions of Lexington County.
