The form does allow you to fill out the questions that you can easily get from the tax return, save the "draft" version, and then go back and fill in the information that was not readily available from the return (or at least it did the last time I completed one.) I don't usually do a pencil copy, but instead fill out what information I have, print a copy and let the client fill in the rest. I will help them with it if they don't understand what is being asked, but I don't generally have information on their bank balances, etc. in doing their personal return.
