Fake experience and bank for a job at Big4 - What should I do now? Will they review my bank statement with the bank?

I had recently attended an Interview at Deloitte USI. I had mentioned 4years experience in my resume. Whereas I worked only for 3Years but have positive contact with my previous employer, So he provided for further 1year. Only issue is I have said that my salary was 20k during last year. I had submitted a fake bank statement of ICICI for that one year. I badly needed a job and I had to do that. Now I cleared all my interview rounds.
What should I do now? Will they review my bank statement with the bank?

They will not go and check in bank unless they have a doubt.
But the act of faking documents is wrong legally and morally
Further advice willbe difficult in this kind of situation
