Can I collect a refund being on Social Security Disability after winning a slot machine jackpot of $1,850.I literally had the casino take out $468.00 Help?

It is not clear whether you are receiving Social Security benefits or if you are getting SSI---those are not the same thing.   There are strict rules with SSI about how much money you can receive from other sources--so when you say "SSI" wants to know about your slot winnings--it makes me wonder which kind of benefits you are receiving.

WHAT IS THE DIFFERENCE BETWEEN SOCIAL SECURITY BENEFITS AND SSI?

If you are receiving Social Security benefits you will get a SSA1099 in January which can be entered on a tax return.   And then you will also enter the W-2G for the casino winnings to show the tax that was withheld.

 Go to Federal> Wages & Income>>Retirement Plans and Social Security  (SSA1099 and 1099RRB) to enter your SSA1099.

To enter the W-2G  or other documents For your Gambling winnings--Go to Federal>Wages & Income>Less Common Income>Gambling Winnings

If you are actually receiving income from SSI, you will not receive a tax document from them at all.   But you can enter the W-2G on a tax return  to seek a refund of the tax withheld.
