If you only get ssi or SS or SSDI or SSA-1099 it is not taxable and you do not have to file a return. Oh, but you do need to file if you get a 1095A for having Marketplace health ins or to get back any withholding taken out.
If you still want to efile a return you can add $1 of interest. It won't affect your return. Enter a fake 1099Int for $1.
Did you get a SSA-1099? That is for Social Security or Social Security Disability not ssi. ssi stands for supplemental security income. It is different than SS. You don't get a SSA-1099 for ssi and you do not report ssi on your tax return.
