If I use my 2019 info for my 2020 return to get the better amount how will it affect my taxes and social security in the future. During filing it says I will be receiving a w2c from my employer once I pay the social security amount. Is this because I used that income even though that is not what I earned in 2020 and will I have to repay any of the amount on my return or will the IRS know that it is because of COVID? Or is it that I have to pay social security on my unemployment?
