I followed this suggestion and marked the Rollover box on the 1099R form. BUT, when I returned to the 1040, the amount was still listed as income. I went back to the 1099R form and under the inherited section I marked the box "treat it as recipient's own (this is treated as a rollover)" I did not change Box 7 from 4. When I went back to form 1040, the amount of the distribution was included in ROLLOVER amount. Hope this helps someone else.
