Assuming your filing status is single then
TurboTax calculates the excess to be $1460.
That would result in a 2018 6% penalty reported on a 2018 5329 form of (1460 X .06 = $87.60.
If never removed then that penalty will repeat for each subsequent tax year until removed. Each tax year must be reported and paid of the 5329 form for that tax year.
If the excess is still in the account then you owe a total penalty of $350.40 for 4 years and will repeat again for 2022 if not removed by Dec. 31, 2022.
