E-File Submittal Process Deadline for 2021 (Tax Year 2020)

I read that you can continue to e-file (the process of actually using an electronic send of tax return) up to November 1, that it was on the IRS Quick Access Library. I haven't found the confirmation of that yet.

 

I do know however, one year this was true, but Turbo Tax locked down the e-file about 2 hours early on October 15th, causing my tax return to be a few hours late (yes, I accounted for time zone differences.)

 

At any rate, I do have an approved extension, I am getting a considerable refund, however, I'm waiting on some 1099-C forms to arrive, and fear I won't have the information prior to October 15th, so trying to stay ahead of this.

 

Please advise if e-file is accepted this year until November.

 

Thank you!
