Royalty Income

I have royalty income from oil and gas.  I do not have income from renting any part of the property on which the O&G income is produced.  However, TT insists that I enter a value for "rents" of my property, and will not accept a zero value.  I received a 1099-MISC, and have entered all information exactly as it is entered on the form.  I keep getting an endless error loop.  What can I do to fix this error so I can e-file my taxes?
