Refunds deposited in shared bank account

So I share a bank account with my boyfriend we are not married but do live together we do our taxes separately (both using turbo tax) direct deposited into our shared account we have a son who I alone have claimed the past two years will they deposit our stimulus checks into the same account? Or will they think it's a mistake and only give to one of us? And which one is likely to get it considering I would received the money for our son? I've looked over the Internet with no luck on the answer
