Are you saying you capital loss i 2017 was NOT able to be used, so it carried forward? If so, in the section about Stocks, Bonds, etc, it should ask you if you have a carryover.
As for your Net Operating Loss in 2018, unless you file an election to "waive the carryback", that loss is carried BACK to 2013 (which you would need to amend in order to claim it).
