I need to fill out schedule r for the disabled

TurboTax checks for your eligibility for the Credit for the Elderly or Disabled. This credit may apply if you retired due to permanent and total disability.  

This nonrefundable credit has income limits. If your filing status is single, head of household, or qualifying widower with a qualifying child, your adjusted gross income (AGI) must be less than $17,500 and your non-taxable Social Security and pension income cannot exceed $5,000. On a joint return, your AGI can’t exceed $20,000 plus a maximum of $5,000 in Social Security and pension benefits. 

For more information, please Guide to Schedule R.
