¹ Total Itemized Deductions are not a sum of the deductions presented. The total represents the returns reporting a value for Total Itemized Deductions (2020 IRS Form 1040 Schedule A, Line 17). Multiple itemized deductions can be reported on a single return. Due to filing discrepancies, the total dollar amount of itemized deductions on the Schedule does not always equal the sum of itemized deductions reported.
