the partnership/s-corp/trust must issue the k-3 info which will be even later. some had said not until August (?). so your choices are to uncheck the k-3 box and file without the info, (when issued there may actually be nothing on the form that affects your return) and amend later if necessary or file for an extension.
however, it's on the k-3 that any foreign tax credit info will be reported.
