prepared printed and efiled return on 4/3/21. Client just got letter adjusting MO AGI and increasing tax. Printed copy shows line 5 $107,315 and line 6 $81,159 (incorrect). Opening the tax return with current updates shows line 5 $107,315 and line 6 $107,315. Worried that I may have more time bombs because of this erroneous calculation. Would like to have affected clients identified so I can be proactive. Would have liked a heads up about the correction when it was made. Would at least like to have an alert to the changed calculations upon entering the return.
