Client is 100% 1099 income earner and pays quarterly estimated taxes. Submitted Form 1040 with Form 1040 ES prior to April 15, 2024 and first quarter tax payments for 2024 were deducted. Client advised income has increased since Q1 and now needs to increase estimated tax payments. Appears the state 1040 ES for Q2 new amount is reflected in the second voucher on the electronic withdrawal but do not see anything reflected for the change in the Federal 1040 ES Q2 payment for electronic withdrawal. Will the electronic funds withdrawal for Federal 1040 ES 2024 only be in the amount of the original voucher?  Should I just have client pay that difference via direct payment to the IRS?
