I have a large casualty loss from Hurricane Helene. My large itemized deductions when taken against my small AGI would have created a large negative Taxable Income amount on line 15 of Form 1040, but turbotax placed a zero on that line. I have filed my return electronically, but how do I document the NOL carryforward. Do I file an amended return attaching Form 172, or just include form 172 in my 2025 return as I claim in the NOL in carryforward years?
