Traditional IRA for retiree with no earned income (married filing jointly)

Turbo Tax is telling me I can take a $7000 traditional IRA and get a deduction (I have no income other than Social Security and investments).  I am retired (68) with no income.  My husband is not retired (62) and we file jointly.  I am not sure Turbo Tax is correct.  I did find one article that said I could still do the tradition IRA because we are filing jointly, but want to be sure.  I believe my husband maxed out his contribution with a Simple Plan.
