From my experience credit karma gives you the wrong AAoA, it only counts open accounts (unless they've changed something recently). So it may be higher than 1 yr 8 mo, but whatever the number is, it gets rounded down to the year. In your case the closed 2010 citi card might actually be helping your AAoA, it just isn't helping your utilization.
