Yes, you will have to amend you 2019 and 2020 tax return to include the 6% penalty on excess contribution on Form 5329 for 2019 and 2020 because you hadn't withdrawn the excess by December 31, 2020.
Please see How to amend (change or correct) a return you already filed for instructions.
On your 2019 return you will enter your contribution under the IRA contribution section and TurboTax will calculate the penalty.
On your 2020 return you will go to the IRA contribution section and continue through the questions until you get the Excess Contribution from prior years screen and enter the 2019 excess contribution. TurboTax will calculate the 6% penalty on Form 5329.
