After filing ch 7 bankruptcy, I have now accepted a new job@140k a year&when I filed made 72k. Do I need to file an amendment

I agree with the prior answer for the most part. There might, however, be an issue if you had this job lined up and knew that your income would be $140k going forward when you filed your petition. In that case, your Schedule I would need to reflect your income and any anticipated changes. But, assuming you had no idea you would get this job, your schedules do not need to be amended. As for your discharge, I really don't understand why you think you would lose it. Also, not telling your lawyer does not really help your situation. Because you have an attorney you really need to consult with him/her regarding how to proceed. Your attorney has a duty to act in your best interest and I would not substitute the free information you receive online for sound legal advice from your lawyer who you paid to represent you.
