Transaction Not Rolling Back C# MS-Access

Question

I wrote the transaction below in C# to insert data into 4 tables in Access. I deployed the application and when one of the users is inserting data, the insert is failing and the transaction isn't rolling back. I can tell that there's a failed insert because the ID column has skipped numbers when I do have a successful insert.

Would you be able to review my code to see what could be causing this? And secondly, how could I test for this prior to deploying? I can't seem to replicate the user error.

         public static void InsertIndividualOwner(TaxInfo taxInfo, OwnerAddress address, OwnerEmailAddress emailAddress, IndividualOwner owner)
    {
        int ownerTaxInfoID = 0;
        int addressRecord = 0;
        int emailRecord = 0;
        int ownerRecord = 0;
        int specialistID = Properties.Settings.Default.DefaultUserId;
        string insertTaxInfoString = "Insert Into TaxInfo (TIN, BIRT, CAL, PIN, DateAdded, ModifiedBySpecialistID) " +
        "VALUES(@TIN, @BIRT, @CAL, @PIN, Date(), @ModifiedBySpecialistID)";
        string insertAddressString = "Insert Into OwnerAddress (ownerTaxInfoID, streetAddress1, streetAddress2, city, stateID, zip, country, DateAdded, ModifiedBySpecialistID) " +
         "Values(@ownerTaxInfoID, @streetAddress1, @streetAddress2, @city, @stateID, @zip, @country, Date(), @ModifiedBySpecialistID)";
        string insertEmailAddressString = "Insert Into OwnerEmailAddress (ownerTaxInfoID, emailAddress, DateAdded, ModifiedBySpecialistID) Values (@ownerTaxInfoID,@emailAddress, Date(), @ModifiedBySpecialistID)";
        string insertOwnerNameString = "Insert Into IndividualOwner (firstName, lastName, ownerTaxInfoID, DateAdded, ModifiedBySpecialistID) " +
