I don’t understand why you needed to lie on your application that you were married. Where is your wife now? USA or elsewhere?
You need to apply i-730 to get her derivative asylum status first and then after one year of her being on that status, she can apply for i-485. She cannot apply directly i-485 just being married to an asylee. If she was present at your interview as your wife, then she would have got derivative status immediately.
