Just finished entering my data for 2020 and the deduction on 1040 line 12 is $2600 larger than the standard deduction of $24800 with no explanation of why. Schd A has no values of $2600 on it and the total is smaller than the standard deduction anyway. Clicking on the line 12 number takes me to Schd A but, as I say, no explanation of how the number comes to be. Anyone know how I can find out how the value for line 12 is determined?
