Did I itemize my deductions?
If you itemized your deductions, you would have a Schedule A attached to last year's tax return. Most people use the Standard Deduction unless they own a home or pay large amounts of state taxes. Itemized Deductions consist of mortgage interest, property taxes, charitable contributions, medical expenses, state and local taxes, and other miscellaneous expenses.
If your Itemized Deductions were greater than your Standard Deduction last year, then you probably itemized your deductions and your 2024 tax return would include a Schedule A.
