@tonbel Take a closer look at those 1040ES vouchers. Those are not for installment payments for your 2019 tax due. Those are optional vouchers to send in with estimated quarterly payments for 2020 tax. There was not a box to check to pay 2019 tax in installments. Your 2019 tax due must be paid in full by April 15, 2020. You should be seeing a 1040V voucher to send in with a check or money order---the amount on the 1040V should be the same as the amount you see on line 23 of your Form 1040.
