Tax Year Prior to 2020: 2019 CA Form 540-ES Payments

Upon completion of my 2018 CA State Taxes, Turbo Tax provided a Payment Form 540-ES 2 and a Payment Form 4 540-ES 4.  In filing my 2019 CA State Taxes, Turbo Tax provided Payment Forms 1, 2 and 4 for use in 2020 and indicated I owed $1,939.00.  Did Turbo Tax not supply the proper number of Payment Forms for use in 2019 and that the owed amount is based on a missing quarterly payment?
