The Department of Foreign Affairs spent over €5,000 on the operation to bring Lisa Smith back to Ireland.
According to the Sunday Independent, the costs covered travel and accommodation for the team of officials involved in the three day mission.
Ms Smith and her daughter returned to Ireland from Turkey in November.
The former Defence Forces member is accused of membership of ISIS - but denies the charge.
She appeared in court on Wednesday, asking for the charge of terrorism against her to be dropped.

It was the Louth native's fourth appearance in court.
The court heard the DPP hasn't completed the book of evidence in the case - with the State's solicitor describing it as 'complicated and substantial'.
Her solicitor told the court there isn't a single piece of evidence to support the charge against her and asked for it to be discontinued.
The case is due back in court in March and Lisa Smith has been remanded on continuing bail until then.
