UNDER PAYMENT PENALTY

Turbo tax is showing that I have a California under payment penalty this year. I did sell my house in California in 2019. I never filed estimated tax returns.
Under Qualified Exception, my 2018 tax liability is> TAX ON LUMP-SUM DISTRABUTION IS 0
                                                                                                                CA INCOME TAX WITHHELD 0
                                                                                                                   EXCESS CA SDI WITHHELD 0
                                                                                                                                2018 AGI WAS 21,847.
With this information, do I still need to pay an under payment penalty? If not how do I make the proper changes to the forms?
