TurboTax is correct. The $1,667 distribution subtracts from your contributions ($3,010 - $1,667 = $1,343) and from your spouse's contributions ($930 - $1,667 but not less than $0 = $0). That's the way the statute requires the calculation to be done. See line 4 of your Form 8880 where $1,667 is required to appear in both columns..
