Net Operating Losses - Didn't waive carryback period

[ABN-89]

Hi helpful community, 

In a previous year, I had a net operating loss for my rental property. As at the time, I was unaware of the rules around NOLs, I did not include a statement in my return waiving my 2-year carryback period. I have also missed the 6-month period in which I could amend my tax return to include this waiver. Furthermore, according to the guidance, I must file my form 1045 for the NOL carryback within the year of the occurred loss which I have not been able to do. 

Now that these  time periods have passed, am I no longer able to carry this NOL forward or back?

If I am able to carry them back or forward, how? 

Thank you so much in advance!

You stated "In a previous year" but did not mention which one. Obviously, except for certain farming losses, you can only carry NOLs arising from tax years ending after 2017 to a later year (forward). Otherwise, you missed the filing deadlines.

You needed to file Form 1045 within one year after the end of the year in which your NOL occurred.

For a carryforward, you needed to file a statement waiving the carryback period by the due date (including extensions) for the NOL year.
