should Dad send that type of documentation in when He mail in the paper form ?


No, it will most likely get lost.  Wait for the IRS to send their letters, usually it takes them 6-9 months to get going.  The tax return just goes to a data punch operator to type in the numbers.  Later, when it is actually assigned to an office for investigation, there will be a human being waiting for the reply to the investigation letter.
