If you can, even easier for you if you have other bidders, remove her bid only

In general, sellers shouldn’t cancel bids on their listings. However, there are a few legitimate reasons for doing so:
A bidder contacts you to back out of the bid.
You cannot verify the identity of the bidder after trying all reasonable means of contact.
You end your listing early.
Note: Bids cannot be reinstated after they've been cancelled.
To cancel a bid:
Go to the Cancelling bids placed on your listing page.
Enter the item number, the user ID of the bid you're cancelling, and the reason you're cancelling the bid.
Click cancel bid.
