If both contribution were for 2018 then indeed you have a 2018 excess that is subject to a 6% penalty that repeats every year until the excess is removed. Therefore, you will have a $330 2018, 2019 and 2020 penalty. If not removed prior to Dec 31, 2021 you will have another 2021 penalty. You remove it with a normal distribution.
You will need to amend 2018, 2019 (and 2020 of already filed) to include a 5329 form that shows the excess and penalty in part III that will go on the 1040 form schedule 2.
