For you:
Under normal tax laws, there is no free money for being disabled or claiming a dependent. These credits can reduce your taxes (if you owe taxes). The dependent credit can pay you some money even if you don't owe taxes, but only if you have income earned from working.
There was a temporary change during the pandemic, but that expired. For 2024, if your only income is SSA, it is not taxable and there are no refundable credits.
However, Turbotax is "free to start" online, so you can always start a return and see for yourself. When you get to the end and you don't owe and don't get a refund, you can stop without completing the filing process.
For someone else who could claim you:
If there is someone else who can claim you as a dependent, you do not need to file a return just for that reason. You only need to file if you have other income that is not from SSA. Your SSA income is NOT included on the other person's tax return.
