The $300 charitable deduction on top of the standard deduction is brand new this year and will only happen for 2020 and 2021. Since this is not a deduction but an adjustment to income it will not be part of the total deductions. Neither will the student loan adjustment be part of the deductions total. It's poor that they put the deductions, adjustments end credits all in the same section which can make it a bit confusing at times. Look at the actual return and don't get hung up on the summary screens.
