Investors & landlords

Thanks.  After entering the Cost Basis amount it asks "Do you know your capital loss carryover amounts?"  I say No, then it asks to refer to my 2016 Schedule D (Capital Gains and Losses).  My 2016 Taxes did not have a Schedule D so is it okay to leave these spaces blank?  It also asks for my Alternative Minimum Taxable Income from Form 6251, I do not have this form in my 2016 taxes so again can I leave it as Zero?
