Investors & landlords

Thank you.  Yes, I have done all that.  I had a loss of $4000 for 2018 for rental.  I had interest income of $6000.  I had a net gain of $2000 before my standard deduction of $13600.  My only other income was small amount of non taxed social security.  I filled out Schedule A form 1045 and believe I have an NOL of $4000.  If this is correct, since it is no longer possible to carryback NOL from 2018 do I need to include the calculations and a note electing to carry it forward?  I am planning to submit by mail.  Did I do it correctly?  Do I need to do anything to carry it forward or will it automatically be carried forward to next year.  Thanks,
