The taxpayer copy that e-signature sends is a joke. Way too many unnecessary pages. Nobody needs or wants all those worksheets that are not part of the return. The days of making a  taxpayer copy thick to look impressive are long gone. What I do is save a filing copy of the tax return with client letter as first pages. Then in e-signature uncheck the box that says send the taxpayer copy but on next screen add a reference document then point to the filing copy I created.
