@classicrockguy I seem to recall this same issue from either 2018 or 2017. Did some checking in Forms mode. And although the program does calculate the correct overpayment on the Form 8959 and enter the amount on Line 24, that amount does not flow to the Tax Payment Worksheet Line 18f, just as you stated.
I will report this to the TurboTax Moderators of the forum and see if this can be corrected. But since it has been this way in the past with no correction, I am not hopeful, but who knows.
Anyway, Thanks for pointing this out.
