Retirement tax questions

If you are filing as Single and as stated you are age 85 then the Standard Deduction on the 2022 tax return for your filing status and age is $14,700.  If the taxable income you have reported on the tax return is less than your Standard Deduction then you will have no federal income taxes owed.

You do not need to file a tax return unless you had federal income taxes withheld from your income then you should file for a tax refund.
