FYI: Had similar issues completing my TurboTax (TT) 1040 because TT software allowed me to manually enter charitable contributions twice. One entry did not override the other. This was the "bug" for me. First, if you are manually entering itemized deductions under "Deductions and Credits", TT is building Schedule A to compare itemized deductions to the "Standard Deduction" for your filing status to determine which is best for you. Second, in a subsequent section when you are informed you can deduct up to $300.00 (depends on your filing status) without itemizing. This amount is added to Schedule 1. After I removed my first manually entered charitable tax deduction under "Deductions and Credits" the software accepted the allowed deduction that does not require Schedule A for itemizing.
