State tax filing

I did a new tax return and laboriously entered all information.When I put in my SE income, I was please to see that a QBI calculation was carried out and a deduction put in. Then I entered my spouse's SE income. After that, both show (in the QBI summary as well the the two QBI components) ZERO deductions. The QBI sections are greyed out. Something worked initially, but then stopped. This is very frustrating. Any ideas? Thanks in advance for any advice.
