I need to amend a 2015 990-T to carry back 2019 and 2020 net operating losses.  Intuit does not appear to have updated the 2015 software to accommodate the new five year carryback.  2016, 2017, and 2018 are the only years available for selection.  I have never done an amended 990-T for an NOL carryback, so am not absolutely positive I am in the right screen to do so.  We checked for any new update and there isn't one.  Is there a workaround?
