Turbotax Deluxe CD software incorrectly detects excess Social Security withholding from multiple W2s

I believe I have found a defect in the Deluxe CD Turbotax software.  Due to some paid leave in 2017 I had 2 "employers" and W2s, the second employer acting on behalf of the first to pay my leave.  The application states: "Erik may have paid too much Social Security tax. You'll get a refund of any excess over the maximum withholding of $7,886.40 on your tax return."  However, my withholdings are $7278.70 and $607.70, which add up exactly to the aforementioned max.  The next screen says I would get $1 back for this.  This seems incorrect, seems like a math bug needing to be fixed.
