How do I tell turbo tax my HSA is a family plan. It's telling me I contributed too much at $6,850, but that's the maximum amount for a family plan. How do I correct?

My wife does not have a separate plan of any kind.  It's only my plan through my employer that covers our whole family.  It appears to be assuming it's a single person plan and I've overcontributed.  If I check my spouse as having HSA, too, then it assumes she has a different plan?
