I found this for Lacerte - I assume it would be the same with PCT.  Possibly you canceled the e-signature?

In-person signing

In-person signing is now available for Lacerte. If you're going to meet with your client in person, you can use this to simplify the signature process by creating the eSignature and having your client sign it on the same computer.

On married filing joint (MFJ) returns, you can use in-person signing for both recipients, or have one recipient sign in-person and the other sign remotely using a traditional eSignature.

Why would anyone use this if you were sitting at the table in person?

Is it like texting to the person you're having lunch with?
