IRC Section 172 (b) (3) carryover election

[JasonTN]

I just mailed in my 2017 tax return about 4 weeks ago (5-29-20). I had an NOL and elected to carry it forward, which is normally irrevocable. However, I have since discovered that my election is way past the due date. I'm thinking this should automatically make the election invalid, and I can just go ahead and proceed with a carryback to 2015. Am I correct in this assumption? How does the IRS normally handle this type of situation? Do they generally regard the election as invalid and require a carryback, or do they generally just accept it anyway? Or do I need to take some other action?

I am hoping I can just move forward with the carryback (as it really is the choice I should have made in the first place as it actually can benefit me) and ignore the past due election as if it never happened, since it should be invalid anyways.

you need to do the carryback b/c the election wasn't timely.
