E-File rejected for Sch 2 First Time Homebuyer Credit Repayment (we never had this credit or repayment)

Our federal e-file was rejected (S2-F1040-394) though we have never had anything to do with the First-Time Homebuyers Credit or Repayment.  Our returns properly showed nothing on that line on Schedule 2.  Turbotax refiling instructions said to go back and correct that information before refiling.  Since it was already correct, all I could do was go step-by-step through that portion of the interview again.  I ran the Review for Errors again, and it still showed no errors, so I resubmitted the E-files today.  If this is a TurboTax glitch, it should be corrected.  If this is an IRS glitch,  we should be warned and clearer instructions for resubmitting should be provided.
