My mom didn’t report income to Medicaid. Looking for advice.

Hello all, back in 2019 my mom, brother and myself were self employed and did gig jobs for some money. We applied for PUA and got accepted. I thought she had told Medicaid that we made that self employment money but apparently she didn’t. She told me that we were on her Medicaid account and that she was responsible for reporting all of our incomes. Neither me or my brother have ever reported income to Medicaid, my mom has done it all my life for me ever since I was little, I don’t even know fully how it works. I’m not even sure if she reported all of the PUA money we made. I have several questions and I’m pretty worried. She has taken us all off Medicaid apparently.

What would happen if she told Medicaid of the income? Would they simply ask her to pay it back, would they charge her with fraud?

Would Medicaid get me involved and try and get me in trouble too even though my mom has always been the one that certifies me? I was not even aware that you had to tell Medicaid of changes of income since my mother has always handled everything. I’m 22 now btw, I know I should know this stuff by now probably but please excuse my ignorance. No one ever sat down and talked to me about this stuff.

Should she contact a lawyer?

Is there anything else I should know and be aware of? Does the public health emergency play into this at all?

Thanks
