How do I change my status to disabled. I’m rated as 100% disabled by the VA and draw SSDI

It asks if I’m blind but not disabled so how do I change that

For disabled adults:

There is an extra amount added to your standard deduction if you are legally blind.   Your federal return does not provide any other credits or deductions for saying you are disabled, with one possible exception.  

There is a credit for the Elderly and Disabled which is so small that very few people benefit from it—-it has not been updated/increased by Congress for decades.

There are some states that provide various credits to elderly/disabled folks, so watch for that when you prepare your state return.   The states that I know of that have anything for elderly/disabled are AZ, CT, DE, IA, MO, ND, NJ, NY, VE.   There may be others.

If the Social Security benefits (SSA OR SSDI)  is your ( and your spouse’s if married) only income then  there is no need for you to file a  tax return UNLESS one or more of these apply :

• You had federal/state taxes withheld that can be refunded
• You received advance premium tax credit for health insurance from the ACA Marketplace (aka "Obamacare") 
• You took money out of Health Savings Account (HSA) or Medical Savings Account (MSA).
• You are married filing a separate return from your spouse and you lived together during the tax year OR   you are filing a joint return and the spouse has income other than SS benefits.
