Change my account number??

So months ago, my mother asked for a void check so she could deposit money into my account. Long story short, she moved from my brothers place to my older sisters house and can’t find the check. So now she’s pressuring me to change my account number to be on the safe side. She told me that she’s pretty sure it’s in one of her boxes... my siblings are telling me it’s fine, not to worry about it. But my mom made me SO anxious about this whole situation that I can’t let her advice go!

So please, I would really appreciate some helpful advice. Thanks everyone 💕

Ps- I am pretty young, so this is my very first checking account and I just opened a credit card account. I’m still learning how to adult 🤦🏻‍♀️
