I should have less tax return than Turbo Tax calculated. How do I modify that?

My husband was a non-resident alien for 2019, so he should not receive the first and the second stimulus checks. But in the Turbo Tax 2020, it calculated his amount to the return tax. How should I change this? Besides, both of us received 1042-S form and I didn't find any where I could put the info in the software. How should I fix this? Thank you!
