Retirement tax questions

I have a similar situation.  My wife inherited the remainder of her mother's annuity at her death.  The distribution in full came to her as a lump sum.  I have the 1099-R and have entered the info in Turbotax.  Turbotax keeps referring to this as "SPOUSE'S IRA"  or "Inherited IRA."  Does it matter that this was an annuity payout?  Are they treated the same anyway?  Thanks
