We would most likely be able to offer a more useful response, if you told us what the errors are, in the order the errors are displayed to you.
When you have a mix of rental income and royalty income, one common error is entering both incomes as a single 1099-MISC entry. You have to enter each "AS IF" you received a 1099-MISC with the income reported in box 1, and then another physically separate entry of the same 1099-MISC, with only the amount entered in box 2.
