Jean, I don't have a Form 8959 in my 2019 1040 'package' (generated by TT) but there are references to it:
For example, while I don't have a reference for Form 8959 line 24, I do see the following in my SMART WORKSHEET FOR: Child Tax Cr and Cr for Other Depend Wks:
E Enter the Additional Medicare Tax withheld (Form 8959 line 22) ... and this line has 0 (zero) entered.
Dan
P.S. And I tried to track down the difference as well ... because line 17 in the 1040 says "Federal income tax withheld from Forms W-2 and 1099" and this has the value 33,808 (instead of the W2 value of 30,534). So I thought perhaps some 1099 had a value of (33,808 - 30,534 😃 3274. But when I search my 2019 1040 (generated by TT) for 3273, 3274, or 3275, I get no hits.
I definitely see why you guys become tax experts. Fun ... but not when you get the IRS notice. Sheesh.
