Interest Deduction

Bought a new main home in April 2019 and put the old home on the market.  Moved in Nov 2019.  Old home has not sold yet.  I entered all interest information.  Average  balance less than $750k.  I entered all interest information.  When done and leaving section, program asks if either of two situations apply, since average balance less than $750k I check no.  The program recalculates taxes.  When I leave this section, the program recalculates again.  It does not give me credit for the interest deduction (the interest amount pushes me into itemized deductions).  If I go back, I have to re-check the "no" answer again.  Why won't the selection stick?  I am stuck in this loop.  I have used TurboTax for years and never had a problem like this.
