2020 Privtae Foundation Form 990-PF
All private foundations do not have to file electroinically, but ATX has the Electroinc Only Filing Watermark on their system for all returns.
Also, their 990-PF does not have an Other PDF paperclip to attach third part documents (i.e., Investment statements), which they will not add to this form. I would think an Other PDF paperclip should be on all return forms.
