Tax filings are a very small part of my practice as a tax attorney, so I do not spend so much time in ProSeries on a daily basis. But I am very diligent about checking the status of the returns I submit. However, I have represented many people in penalty abatement requests because their tax preparers did not notice a rejection notification and have had issues where the IRS did not process a return even though the e-file status shows that it was transmitted to the IRS or accepted (there are even Tax Court cases with similar situations).
