You need to update the excess in TurboTax before printing the PDF. This way TurboTax will correctly recalculate all the totals.
I'm using Turbotax Desktop, so not sure if it's the same in the online version.
In the desktop version, switch to forms, go to "1040/1040SR Wks" and scroll down to Schedule 3 Line 11. Just above that line there is "Excess Social Security Smart Worksheet" where you can override the amount and it should flow to Schedule 3 Line 11. You should also see it reflected in Line 31 of Form 1040.
Once you do that, TurboTax will complain that this credit is incorrect, and won't let you e-file anymore, but now you can print and mail the form with the corrected amounts.
The statement said that I received payments from two customers of the same PEO. According to regulations, the PEO applied separate annual wage base to payments received from each. Then they issued a single W-2 since W-2 instructions do not provide that more than one W-2 should be issued in this case. Accordingly, there was no over-withholding or error, and I should be permitted to take credit on Schedule 3 just like any other employee that performs services for more than one employer during the same year.
