1099 on SSDI

Does anyone know when you get a 1099 on SSDI? I worked on my SSI to get SSDI finally but my income is really low (1100/month) and thought it was dependent on how much you make on it (20-25k or higher potentially) but wasn’t sure if 1099s on SSDI are for everyone on it or just some people depending on income? Anyone have any info on this? Does it mean you have to pay the govt taxes back some benefits and do your taxes every year?
