I'm checking to see if I qualify for the EITC as a disabled person with an income other than social security

[LindaA]

You may qualify for an Earned Income Tax Credit (EITC) if you have earned income and your adjusted gross income (AGI) does not exceed the threshold for your filing status. The IRS defines earned income as:

• Taxable income you earned as an employee, such as wages, salaries, commissions, and tips;
• Profits from operating your business or farm;
• Long-term disability pay, if received before the minimum retirement age;
• Union strike benefits;
• Nontaxable combat pay (code Q in box 12 of your W-2) you elect to treat as earned income for the EIC.
  

Please see the FAQ below for the qualifications for the Earned Income Credit (EIC or EITC). https://ttlc.intuit.com/replies/3299933
