Mr McGovern, 19, who was from Co Monaghan, died after a night out in Omagh, Co Tyrone.
During one attack, he fell to the ground and was left unconscious. He was found dead in bed the next morning.
The 21-year-old woman is facing a charge of perverting the course of justice and is due to appear at Omagh Magistrates' Court later this month.
She is the sixth person to be charged in connection with the death of Mr McGovern.
