The winning ticket was bought in Metairie, WDSU reported.
After realizing they had a winning ticket, the Ehrenbergs panicked, believing they had missed the deadline to redeem it.
"I kept waiting for something to go wrong," Harold Ehrenberg told WDSU.
The Ehrenbergs received $1,274,313 after state and federal tax withholding, lottery officials said.
"We don’t have any plans to buy anything crazy or go on any big trips,” Tina Ehrenberg said at lottery headquarters.
"The most fun is going to be depositing that check," Harold Ehrenberg said.
