It is not clear what you are trying to get. The SSI you received is not taxable and does not get entered on a tax return. If you did not receive the stimulus checks for 2020 or 2021 then you could file tax returns to get those; however, recipients of SSI were supposed to receive the stimulus checks automatically. Did you get them?
Did you have a dependent child under the age of 18 in 2021? If so, you could get the child tax credit for that child. If anyone else claims you as a dependent on their tax return, you are not eligible for any stimulus checks or tax credits, though. Provide some details. But do not post your email or any personal information here. This is a public web site that can be seen by anyone.
