MAGI calculation in TurboTax is not correct for 2019

I have entered the preliminary data for my 2019 taxes (TurboTax Home and Business, Windows).

 

The MAGI (modified adjusted gross income) calculation from TurboTax is incorrect. TurboTax reports my MAGI as equivalent to my AGI. I have some self-employment income, and TurboTax is not adding back the 1/2 self-employment tax deduction to my AGI when calculating the MAGI, per the IRS rules. This error is visible on the "IRA Worksheet" form.

 

This matters because TurboTax is overstating the amount I can deduct from a traditional IRA contribution. (I am in the phaseout range.)

 

Please correct the MAGI calculation and post a software update.
