You do not get a SSA-1099 for ssi. ssi is not Social Security. You only report a SSA-1099 for SSDI and Social Security.
A lot of times people say ssi when they are getting Social Security. But ssi actually 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.
