Sorry you can't include them on your 2025 return. You would have to amend each year to add them. Did you take the Standard Deduction those years? Would you have enough deductions over the Standard Deduction to itemize?
For 2024 the standard deduction amounts are:
Single 14,600 + 1,950 for 65 and over or blind (16,550)
HOH 21,900 + 1,950 for 65 and over or blind (23,850)
Joint 29,200 + 1,550 for each 65 and over or blind (30,750/32,300)
Married filing Separate 14,600 + 1,550 for 65 and over or blind (16,150)
For 2023 the standard deduction amounts are:
