How do I edit the tax liability and AGI it asks for under Underpayment Penalties section after I put zeros in. Tried deleting the form and logging out and in, didn't work

Under the "Underpayment Penalties" section, it asks for 2018 tax liability and Adjusted Gross Income. I put zeros in both of them and now I can't change the amounts. It just continues to tell me I don't owe anything. I tried deleting the form and logged out and back in and it still says the same thing. How can I change it?
