If you had no taxable income--and living off of savings is not taxable income--then you have no reason to "report" your property tax. Without paying tax during the year, there is no reason to file, and nothing to be gained by entering property tax paid on a tax return. You cannot receive a tax refund based on property tax you paid. Entering property tax paid can only help if you actually paid (or had tax withheld from income you received) tax during the year, and you have enough itemized deductions to exceed your standard deduction --- which for a couple filing a joint return for 2020 will be $24,800.
