First time e-filing my parents' joint return

I have completed my parents' joint tax return using Turbotax Home and Business 2020. This is the first time my parents have used any Turbotax product for their return. The return is complete and I am ready to e-file. Turbotax is asking me some questions for identity verification. One of the questions is about whether they filed together or separately. But the next question is confusing. When I selected that they filed together, it then asks me for the AGI of first my dad, and then my mom SEPARATELY. I don't have separate AGIs because there is only one AGI for the two of them. Do I answer the same total AGI amount for both my dad and my mom, which would be their total AGI? It ells you not to guess, because your return could be rejected. I don't know why it asks for each parent's AGI separately when 2019 was a joint return. I don't want to guess. Does anyone know what I should enter s the AGI? Thanks
