This comment from @Rare contributor on the thread you referred to:
https://ttlc.intuit.com/community/tax-credits-deductions/discussion/re-form-1116-htko-negative-numbe...
describes the same issue with printing/PDF generation:
> That is, with copy 2 of form 1116, which is for General Income in my case, if I try to print/save it to PDF, page 2 (the one that contains Part III and Part IV), does NOT get printed/saved !
It's unclear if it was solved or worked around.
