Inherited IRA

When filling out the IRA 1099-R information, toward the bottom, it gives you some choices under the title: Inherited IRA or Type of IRA."   I have an IRA which is my own, and did not inherit.  If I choose the option of "Treat as recipient's own (This is treated as a rollover)," I end up paying less taxes. 

I can't see anywhere in Turbo Tax where it asks if an IRA was inherited, or did I miss that? Would IRS flag my return if I claimed to have an inherited IRA, when in fact, I did not?  Thx
