For some reason when a client chooses to pay their estimates electronically, the federal ES instructions disappear when we jump to forms.  If they are paying by check, then the instructions are available.  Also, there is no issue with the ES electronic payment instructions for the state (CA).  I contacted tech support over two weeks ago.  The steps the tech provided did not resolve the issue and they ended up taking a copy of the file.  We have created an ES instructions letter to provide to our clients who are paying electronically.
