Whoa! What are we talking about? About your 2019 return or 2020? Did you get the 4 1040ES slips? Those are not to pay your tax due. Those are to make estimated payments for the NEXT year so you don't owe so much again. The 1040ES are optional to pay and the IRS will not be expecting them.
You still need to pay any tax due. To pay the Tax Due you either put in your bank info for the IRS to take it out or there is a 1040 V voucher to mail in with a check or you can pay the IRS directly online.
