I Ordered A Package On Amazon With My Moms Bank Account?

I ordered a couple packages on amazon using my moms bank account that she doesn’t use anymore. little did I know she can see the charges. anyway, she was talking to my dad & I heard her say that there’s somebody stealing her identity and they’re buying stuff on amazon! so i panicked because I’m pretty sure that it’s me that “stole her identity”. but she said that the person lives in Georgia and they know her social security number but I don’t live in Georgia and I don’t know her number. so I’m very confused? this might be a confusing question but I’m 1) wondering what I should do about when the packages come and what I should say and all that (all that I ordered were phone cases) and 2) is the person stealing her identity me?! because I don’t live in Georgia or anything. I feel really bad now about ordering all that stuff but I can’t cancel the orders or anything so I don’t know what to do! I’m kinda freaking out because I’m scared I’m gonna get in big trouble. please help!
