Mahalo for the form completion guidance. In 2019 I did charitable contributions and AMT and NIIT so these will affect 2020. I like your idea of using TT to prepare multiple years 1040X and transfer to 1045 and appreciate the warning about processing delays.
Looking at the "what to attach" when submitting the 1045 the instr say to include AMTNOL (alt min tax net operating loss) or ATNOLD (alternative tax net operating loss) calculation. Is this calc part of the 1040x? - I'm hoping it might be attached to it.
This calc is in addition to 6251 Alternative Minimum Tax (original and revised) for each loss year.
