TurboTax is correct. Only the spouse with lower compensation can use the other spouse's compensation to support an IRA contribution. Since both of you have the same compensation, neither of you is eligible to use the other's compensation to support an IRA contribution.
Further, your net earnings eligible to support an IRA contribution are net profit minus the deductible portion of self-employment taxes. With each of you having $2070 of net profit, each of you is eligible to contribute to a Roth IRA a maximum of $1,924.
To avoid an early-distribution penalty, by the due date of your tax return you must obtain an explicit return of the $2,076 excess contribution.
To maximize combined retirement savings, your wife can contribute $1,924 to her Roth IRA.
