E-file electronic filing deadline with extension if I'm getting a refund? Can I e-file past midnight tonight (like a couple days)?

Hello-

 

Rushing to get my small business and rental property 1040 filed by midnight tonight.  I am expecting a modest refund.  I made an additional estimated tax payment with my extension on April 15 just to be sure.

 

Will I be able to e-file my 1040 via turbotax windows 10 - home and business version  -  after midnight tonight Oct 15 (since my taxes won't be considered late by IRS with a refund due)?   I remember a prior year when I tried to e-file in late October and it wouldn't let me saying efile had closed for the season.  But my research seems to indicate I have a week or so past the October 15 e-file/extension deadline to actually e-file through turbotax - and along to the IRS.

 

Can I rely on this? 

 

my returns are complicated for an individual and I'd prefer to have a little more time rather than rush to get them e-filed by midnight if I don't have to (if turbotax will still transmit my e-filed 2024 return in a day or two more).   AND I REALLY REALLY DON'T WANT TO HAVE TO PAPER FILE.

 

thanks for any info you may have on this!
