The 3rd party designee box is checked on Form 1040 and there is no Schedule 6 according to Lacerte and the PDF copy which the client signed off on. I contacted the IRS to assist the client in resolving a matter and was told that the version they received (efile) does *not* have the 3rd Party Designee box check; there *is* a Sched 6 and it indicates that they may *not* speak with a 3rd party. I am absolutely certain that no modification was made to this return by me and I am the only person in my office with access. How is it that what I see in the software and on the PDF differs from what the IRS received?
