I think my tax paper was accidentally thrown out. I'm 61 ,in2024 I recieved $46 on ssi & $918 on ssd dissability.No dependants. What deductions are they talking about?

If Social Security  is your only income, you are not required to file a tax return.    There would be nothing to deduct if no tax was withheld from your disability benefits.   

Who has to file?
