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

[erikmjohansen]

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.

Please run a software update.

Are you saying you just fixed it?  Because I just installed two hours ago and it updated itself at that time.  Thanks.

Yeah, just checked and I am already up to date.

TT uses the IRS rounding protocol.

$7278.70 gets rounded up to $7279, and $607.70 up to $608.  So the total is $7887.

That is $1 more than $7886 (rounded down from $7886.40).

Do not fret over $1.

Feels like I'm stealing a dollar from the IRS, but now that I understand what's going on behind the scenes I'll accept it.  Thanks a lot!
