Do I use Schedule E for farm land rental and expenses or Form 4835 or both?

It depends on whether you receive cash payments or a share of the production as rent.  Use:

• Schedule E, if you are receiving fixed cash payments for rent; OR
• Form 4835, if you received a share of the production as rent.  

Fixed cash payments

Fixed cash payments count as rental income.  Enter the farm as a rental property, reported on Schedule E.   To do this, you need to be using the TurboTax Online Premier or Self-Employed editions, or one of the TurboTax desktop (CD/Download) products.

1. Click on Federal Taxes > Wages & Income  [In TT Self-Employed:  Personal > Personal Income]. 
2. Scroll down to the Rental Properties and Royalties section and click on the Start/Revisit box.  
3. On the Income from Rentals or Royalty Property You Own screen click Yes.
4. If you have already started adding information about your rental, you will come to the Rental and Royalty Summary screen.  Click on the Edit box next to the property.  Or you can click on the link Add Another Rental or Royalty.
5. If you haven't entered any rental or royalty information you will see the screen, Is This a Rental Property or Royalty?  be sure to mark the radio button next to Rental Property.
6. Continue through the screens, entering the requested information.
