You can qualify for the 3rd Stimulus $1,400 check if you didn't already get it. You will have to file file a 2021 return to get it. Since SSDI is not taxable you might need to enter $1 of interest to be able to efile or you can print and mail your return. Just make up a fake 1099-INT. Did they take any withholding out of your SSDI? You can file to get that back. Did you have any other income? Like W2 or any other 1099?
