I have a farming net operating loss in 2021 that I would like to carry back to 2019.  The NOL carryback is limited to 80% of 2019's taxable income.  I have not been able to get Lacerte to limit the carryback to 80% of 2019's taxable income without using the override (it carries back 100% of 2019's taxable income without overriding).  Using the override generates a critical diagnostic error that indicates the return can't be filed electronically.  Is there a way to get Lacerte to limit the carryback to 80% of taxable income without using the override?

Thanks
