@JamesG1, the software did know that I was taking the std deduction. And I did enter $2200 into the donations to charity. The top of turbotax showed the correct amount I owe the IRS, with $600 on the 1040, UNTIL I hit the Review button. At that point, the amount I supposedly owe changed by the equiv of the difference between $300 and $600 in deductions. and the 1040 showed only $300. I did a work around and changed the 1040 form to show $600 instead of $300. It appears there's an error in the Review section for Marrieds Filing Joint.
