Will an Inherited IRA (with no basis) impact my Form 8606 for my own IRAs?

Specifically, on line 6 and line 7, which asks for the "value of all your traditional, SEP, SIMPLE IRAs for year X" and "distributions for year X"  do I include an inherited IRA in these amounts?  Also I have been receiving distributions from the inherited IRA for a few years now, but have not filed a Form 8606 for it, as it was all pre-tax money, is this correct?
