anyway to change estimates already set up in efile

[schirallicpa]

My client had an unusually good year and needs to increase the Jan payments.  But these were set up in efile in April and are already set.  Is there any changing this or do we just go online and made 2nd Jan payment?

I think the client has to call to change.

Just tell her how much additional to pay and have her do it via IRS's DirectPay.

Or if she's within one of the safe harbors, just tell her how much to save to pay with her returns.

The client can always go to Direct Pay and pay in the difference.  You wanted to add $500 to the payment?  Pay $500.  They will happily take the money.
