Advice please

So my mom “accidently” claimed me as a dependent for 2019 taxes last year. She filed an amendment to take me off and when I tried to file taxes for this year it got rejected because my amendment is still pending. I had a baby in dec of 2019 and I haven’t gotten any unemployment, no stimulus checks and I’m messed up financially. I don’t know what to do. Me and my mom got into a huge fight, I have no contact with her and I found out that dependents get stimulus checks this year.. it’s not fair if she gets that money. What can I do?
