The Seventh Card

Anita is playing in a Grand Prix Trial. She calls you to the table and informs you that she was resolving a mulligan to 6 and made an error. She tells you she was on autopilot and counted out 7 cards face down on the table. She then drew cards 2, 3, 4, 5, 6, and 7. At this point she realized she was only supposed to have 6 cards in hand and called you. Card 1 is still face down where she placed it when starting her count. What do you do?
