I don't know about SSI, but this isn't accurate for SSDI.
For SSDI, if your earned income is more than $1110 in a month (for 2024), then you consume one of your 9 trial work months. That $1110 threshold is regardless of your SSDI payment amount and it is adjusted annually. The trial work months are to allow disabled persons to attempt to return to the workforce without risking losing their social security benefits if it proves unsustainable for them.
(The specifics are a little more complicated than what I've described.)
