After you file

Sorry, but the 24-48 hrs is really only during the main part of the tax season....usually first-or-second week of February onward...the first week-to-10 days can be much slower.   Some get lucky and theirs gets pulled right away.

 

The IRS has control (well, their computers) and pulls random groups of files from all the Software providers....but only what their computers can handle without crashing.

 

Because of that randomness, some folks have friends who waited to file until right after the IRS started.....and their files get accepted BEFORE someone who had filed in early January.  It's not First-in-First-out.
