YLC - when you were a young kid going to school, did you go to school the first day at 5:00 in the morning wondering where everybody was? Or did they have a specific time that the school opened their doors?
Same applies for me -- I attempt to efile a return and nothing happens. My 2020 returns at least show they have been sent to Intuit.
And, since the IRS and ProSeries announced returns would be allowed to be efiled starting on February 12th without specifying a time, my assumption was that it means it would be allowed at 12:01 AM this morning.
