Need to amend scheduled estimated tax payments. Where do I find the "Input Return" tab as instructed.

[sjrcpa]

If they have already been scheduled for electronic payment through the software via an efiled accepted return, you can't change them through the software now.

You'd need to call the phone number on the 8879 to cancel any payments you have scheduled, then re-schedule them on the IRS Direct Pay website.

You can't "amend" an estimated payment.
