Out of 2, 1098-T docs for my 2 sons, for one of the docs, in spite of entering "FILER's Federal Id", Turbotax is repeatedly asking me to enter it. Won't let me proceed.??

Two sons in Univ with 2, 1098-T filled completely.
During review, one of the 1098 repeatedly asking to enter "Filer's Federal ID". Won't let me proceed and submit. Is it a bug in Turbotax ??
