I received a 2020 SSA 1099 for disability. Box 5 listed the total monies paid to me in 2020, $20,691. Box 3 lists 2019 money $6015. At the review section of my Federal under income...I can see the breakdown of the SSA income as $15,504. The math does not compute for me. There is a difference of $828. Can someone explain this difference. This is my first year on disability. thank you
