1099R taxation of life insurance death payout

Thx for your reply.  Confirmed what I thought.  I have been trying to contact the employer for 2 months now to see if they were in error or if there was a possible exception to the non taxable status that I did not know about.  No response until the day after I filed the return.  TurboTax has a drop down menu for box 7 which does not include code 0.  I am a volunteer for AARP Taxaide program which uses a different software that does allow code 0.  So I filed with that software, putting in the 1099 as I had it and the death benefit was taxed.  Figured I could amend once I finally heard from the employer.  Their response was that they had made an error and I was sent a corrected 1099.  This one shows no taxable amount, total distribution box checked, Sep/IRA box not checked and still code 0 in box 7.  The IRA must have received the same correction, since the tax amount owed was adjusted to the correct (non taxable benefit) amount.  I had put in an automatic debit request so I saw what was paid.  Amazed that the IRS fixed so quickly, unless something happened because of the code 0 on the initial 1099.  Once again thanks.
