"Do over" of social security payments received in 2019.
I am still working, and last year (2019) I started receiving Social Security at full retirement age of 66. I decided to do a stop payment, that that ended my social security checks in December of 2019. I paid it all back in January of 2020, and hope to do a " Do Over" in 2020 with the income of 2019 averaged in my last 35 years of working full time, and recalculated. Am I still taxed on the funds received in 2019, but paid back in 2020? My personal bank can tell that the cashiers check I sent to the Social Security Administration has not been cashed yet, as of 2/13/2020. According to TurboTax, I will pay the IRS an additional $2400 if I cannot claim the "payback" check I sent. I am still working, and plan to keep working. Ouch!
