Easiest way - Cancel the bill and go back to the client information. Go to funds tab and open the funds account. Check the box that says something to the effect of automatically pay new charges on bill. Make sure show on bill is set to detail. Now run the bill.

Other option is to enter a withdrawal from funds transaction and then enter a payment since the bill is not yet approved. 

Thank you. I will try this at work tomorrow. I am totally new and the previous person was let go and now I am stuck having to figure it all out with no user manual at all. Another dumb question, howdo I cancel the bill?  Thank you so very much. I appreciate your time ️

Depends on if approved. If approved you have to go to bills approve or clear and undo. If if in proof same place but clear from proof. 

Thank you for your help, ️️
