Information at the lottery's website shows that one ticket sold in Florida is worth $3 million while three others are worth $1 million.
The six winning numbers drawn on Tuesday night were 5, 28, 62, 65, 70 and 5 again as the special Mega Ball.
Anyone who hits all six numbers to win the jackpot can choose an immediate cash payment of US$904 million or receive the US$1.6 billion prize over 29 years.
The jackpot's cash value was $878 million, an option favored by most winners. Mega Millions reports 36 second prize tickets were sold, which matched every ball except the Mega Ball. That game itself now has a monster jackpot, though a small one relative to Mega Millions: Powerball stands at $620 million ahead of Wednesday's drawing.
One was sold at a Circle K on Harrison Avenue in Cary.
The jackpot had been rolling since July 24, when a California office pool of 11 co-workers shared a $543 million prize.
So who won the jackpot in SC? If no victor is selected in Tuesday's drawing, the jackpot will increase to $2 billion for Friday's drawing.
Odds of winning the prize were 1 in 302 million. The previous record was a $1.586bn jackpot for a Powerball draw in 2016.
Mega Millions tickets are $2 and are sold in 44 states, Washington, D.C., and the U.S. Virgin Islands.
Mega Millions announced the historic win in a statement early Wednesday.
The lucky player overcame miserable odds: the chance of matching all six numbers and winning the top prize was 1 in 302.5 million. Seven others in the state won $10,000 apiece.

One ticket sold in SC matched all six numbers in the Mega Millions lottery draw for a record-setting $1.6-billion jackpot, the state's lottery says. Last October, those officials made two big changes: They doubled ticket prices to $US2 - and tweaked the formula to make it easier to win smaller prizes but harder to win the jackpot.
"A big mistake people think: this is a lot of money so let me help everyone", Laurie Ruckel, a trusts and estates lawyer at Loeb & Loeb law firm in NY, said yesterday.
In March, a New Hampshire judge ruled that a $560 million Powerball jackpot victor can stay anonymous after she sued the state's lottery.
