But a mature female will lay eggs regardless of whether or not there's a male around, they just won't be fertile. And if a female has mated with a male, she can still lay fertile eggs for around three years after having done so.
Your turtle needs have proper nesting area to lay eggs in rather than just let her deposit them under a beanbag chair or wherever. A good site for info why this is important and how you can make one for her can be found at http://www.tortoisetrust.org/articles/Nestsites.htm
