I select review on my state taxes, I get an error. It asks me to enter total rent paid. I do that. I still have have 1 error telling me to leave it blank. It is a cycle.

It tells me to enter the information on line 6 for total rent paid. I do that. It then tells me to leave line 6 blank. I do that. It tells me to enter total rent paid. It keeps going on and on. What am I missing?
