I believe we must clarify a few things. Only a person with access to the ward finances (a member of the Bishopric or one of the proper clerks) can check the account. If your daughter checked the account then that means she received information from one of those individuals. But those individuals are not allowed, under policy, to tell your daughter about anyone else's donations. They could give her an account balance but not any details about anyone (other than herself) who contributed to the account.
The only way to confirm where some other donor's donation went would be for that donor to request her own donation records (or, perhaps, look it up online herself, but there are some reports floating around that the online record and the local, ward computer's record might not always match… because they're still working bugs out of the system, I suppose). If that donor can confirm that her donations went to the wrong category then she can request a correction. Otherwise, according to policy, you don't really have anything to do with her donations.
So my advice is: Tell the other donor you think there might be a problem and that she should ask for a printout of her donation records. Everything else is really out of your hands.
