The 1045 is to carryback the NOL to prior years. It must be filed by the end of 2019 for a 2018 loss. You now need to file a 1040X for each of the years of carryback. See the instructions for 1045 https://proconnect.intuit.com/community/help-articles/help/generating-individual-schedule-c/00/5195 and 1040X https://www.irs.gov/pub/irs-pdf/i1040x.pdf
