Homebuyer credit repayment keeps trying to delete form 5405 if I enter that we sold the house prior to 1/1/2016

We bought our house in 2008 and have paid back $6,500 of the $7,500 credit. We bought a new home in 2015 and our old home stopped being our primary residence before 1/1/2016. We sold our old home in early 2016.

Each time I select that our old home stopped being our primary residence prior to 1/1/2016 TurboTax tries to delete form 5405. Why?

If you actually sold the old home in 2016, use the closing date as the date you moved out.  It's close enough, will give the correct result, and much easier than trying to amend the 2015 return.
