It took a few years to fine tune but I print only a Client Copy and with it I add W-2 Worksheet, Interest and Dividend Summary (but trash it if not tax-exempt, qualified or other info), tax-exempt interest summary, Qualified Dividend and Capital Gains Tax Worksheet, Form 1099-R Summary, Social Security Benefits Worksheet, Student Loan Interest Worksheet, Medical Deduction Worksheet, Charitable Contributions Worksheet, Tax Payments Worksheet, QBI, Recovery Rebate Worksheets.  Each as applicable and trash if not important info.  If desired for other returns I might add a worksheet here or there to aid in their review.  This is a personal choice but I like showing calculation worksheets.  That way the client doesn't have to ask my Social Security Benefits were $20,000, why was on $17,000 taxable.
