Deductions & credits

It does make since that online would get updated faster. Since the data and software used is on TT server. Where as desktop user would see a delay. Because the updates are coming from TT to your desktop where it be a Mac, Windows.  There are extra hoops they have to go through for us desktop users like making sure the update does not crash your computer. Personally I prefer desktop due to I'd not want my taxes to be on some cloud server. But that is my preference.
