I'm adjusting to the program updates in Pro Series 2020.

When I try to electronically file a return, I get the following message:

"You don't have sufficient funds to authorize these returns. Click "Authorize" to add funds to your account"

Did I miss something? I have no idea what this means? I don't understand this message, I've always purchased a package large enough to include filing all the returns I expect to prepare. 

Also, do I need to request an electronic signature from the client before I'm able to file on their behalf?
