okrandy, you've contributed the correct maximum total between you and your wife.
On the page where you list your individual coverage type for each month, TurboTax presents the individual's contribution limit without taking into consideration the spouse's contribution. If you indicate that your wife contributed $1,334 (her individual limit without regard for your contribution) after having indicated that you contributed $8,000 to your own HSA, on the next page TurboTax would indicate that between the two of you you have a $1,167 excess contribution and would ask you to select he one(s) who made the excess contribution(s) totaling $1,167.
