How can I ensure the depreciation is prorated to my percentage ownership?

I own 50% of a rental.

I selected Turbotax to calculate my share of expense/income, and enter the full amounts.

Turbotax calcuates 50% on the income/expenses, but does not prorate depreciation expense on Schedule E line 18. 

If I manually overwrite by dividing by 2, Turbotax mentions I cannot file electronically if I overwrite.

How can I ensure the depreciation is prorated to my percentage ownership?

 

Thank you!!
