Are underpayment penalties forgiven in 2021?

A month ago I filled in my Turbotax return and based on under-withholding due to special income this year, my withholding was quite deficient.   Turbotax said I owned a penalty in addition to the amount I owed for Taxes. Tonight, I re-calculated my taxes and I can find no entry in Turbotax for the penalty it formerly said I owed.
