I do not see how the Foreign Earned Income and Exclusion on Form 2555 could have caused the increase of taxes so have ruled that out.
There must be something listed in your tax forms, schedules on the left side of the screen which would affect the taxes owed on Line 16, but right now I am at a loss. Usually the explanation is because of additional taxes from Schedule 2. Or Self-Employment taxes.
My suggestion would be to save this tax return and start another with the same information and see if you get the same result. Rename the name for this tax return in the File menu located in the upper left of the desktop program screen and click on Save As...use a name that will identify this return so if you start a new return it will not overwrite this return. The tax file name always starts with the Last Name and then the First Name Initial from the first person on the tax return.
Otherwise you could send a redacted tax file to TurboTax support so they can do an investigation.
One of the TurboTax Expert employees can ask for the redacted tax file. You would only need to click on Online at the top of the desktop program screen and then click on Send tax file to agent
@MayaD Can you or one of the other Tax Experts look at this tax file when sent?
