Did you schedule them at the IRS to come directly out of your account? Did you enroll with the EFTPS system? https://www.irs.gov/payments/eftps-the-electronic-federal-tax-payment-system
The 1040ES estimates are optional to pay. The IRS won't be expecting them. You can just stop paying them or cross out the amount and write in a new amount.
