Get your taxes done using TurboTax

You are either really close or have it.  They should be on the same sch E. You should only have one Sch E but will also have worksheets.

Box 1 rent does create a Sch E page 1 for renting out the right to explore.  

Box 2 royalty does create Sch E page 1 for royalty income. The royalty is listed as code 6 for property type on line 1b.

Reference:  Instructions for Schedule E (Form 1040)

Here are some screenshots. I have two royalties listed with the rent.
