Unable to change Rental Real Estate Recovery Period under assert entry worksheet

Hi,

For depreciating a Residential Real Estate property, I am using StraightLine MACRS method.

I am also using TurboTax Delux Desktop.

For some reason turbotax does not allow me to change recovery period to 27.5 years. It selects 40 years and the box color is black, meaning I cannot modify it.

Also MACRS convention is set to MM and box color is black.
