Fifteen other officials, including former president Win Myint and the chair of the election commission, faced the same accusation, the report added.
Myanmar has been in turmoil since a military coup in February sparked nationwide protests and a deadly crackdown on dissent.
Convicted from the coup, Suu Kyi, 76, faces a variety of charges including the illegal importation of walkie-talkies, sedition and corruption, and faces decades in prison if convicted.
She is already on trial for violating coronavirus restrictions during the campaign ahead of the elections, in which she National League for Democracy party (NLD) defeated a party deployed to the military.
International observers said the 2020 polls were largely free and fair.
The junta threatened to dissolve the NLD and last month jailed Win Htein, a close aide to Suu Kyi and a high-ranking leader, at 20 on charges of treason.
More than 1,250 people were killed by Burmese junta security forces since the coup and over 10,000 arrested, according to a local monitoring group.
