No the property tax won't give you a deduction by itself. Not until all your deductions are more than the Standard Deduction. Deductions can only reduce your taxable income to zero. But you don't need any deductions since you have zero income. Entering $1 of interest won't change your return but will give you some income so you can efile. Otherwise you will have to print and mail your return. And you do not want to mail! That will take forever to process. The only way to get the missing Stimulus is to file a 2020 return.
