Just a stab in the dark here, but couldn't these refunds be 1 for Federal, 1 for State refunds for the primary account owner and the 3rd refund might be federal or state for a minor child? Or if the account is a joint one and (for example) the husband and wife file separately, I could easily see there being 3 refunds.
I'm not a lawyer nor do I work for the IRS, so I'm not positive, but I was under the impression that you can have your refund direct deposited to any bank account you choose, so a minor might choose a parent's account if they don't have one of their own, I should think.
