So I am NOT an expert. But after going through the questions about 10 times and making sure the fields were filled and getting nowhere, I clicked on the form from the review. It has the "z" in red. If you go up the form, you can see were there is supposed to be entries for income/rental income, etc. Even though I filled those out in the questions, they did not show up on the form. If you add them directly onto the form, the error goes away.
