That's been 20yrs or longer since I got disabled I was told I didn't have to file anymore is that true
That depends on if you earned or had other investment income.
If you only had disability, you are not required to file a tax return.
Being disabled does not exempt you from filing a tax return if you have taxable income that is over the minimum amount for filing.
Go to this IRS website for who needs to file a tax return - https://www.irs.gov/newsroom/who-needs-to-file-a-tax-return
Do you have taxable income from work, interest, dividends, investment sales or the like?
