In New York State, three other second-prize tickets were sold - one on Long Island and two in Brooklyn.
All four tickets matched the five numbers drawn Tuesday night while the $3 million victor also matched the mega number, 5.
In Ohio, a Mega Millions ticket worth $1 million was sold at Bee Gee's Minit Market in Kettering.
The $1.6 billion jackpot translates to a one-time payout of $904 million before taxes, or 30-year installments that start at $24 million, and grow to more than $99 million by the final annuity.
The jackpot's cash value was $878 million, an option favored by most winners.
The winning numbers were 5, 28, 62, 65, 70, with a Megaball number of 5.
The jackpot got so big because no one had won since July, when a group of office workers in California shared $543 million.
It's possible that we won't ever know who the victor in SC is.

While many states still require jackpot winners to claim their prizes publicly, the tide seems to be turning in favor of winners wanting to fly under the radar. We haven't seen a jackpot this big since Powerball hit $1.6 billion back in January 2016.
It will likely be days or even weeks before a victor steps forward to claim the prize. The ticket was sold in Palmetto State.
Regardless, it's the largest single winning ticket ever and it dwarfed the previous Mega Millions record, set in March 2012 at $656 million.
Following the historic win, the next Mega Millions jackpot was estimated to be worth $40 million, according to the game's website.
It costs $2 (£1.50) to play the game but the odds of winning the grand prize are 302.5 million to one.
Although Tuesday's jackpot was extraordinarily large, it was no fluke.
Mega Millions has already smashed its own jackpot record. Not too shabby, either.
Mega Millions officials say at the time of the drawing, the jackpot was $1.537 billion, just short of the record for all lotteries.
The Powerball has climbed since the last victor in NY in August, and has had 20 drawings since then without a jackpot victor.
