As of the end of 2017, there was no longer an option to forgo the carryback, since you were'n t allowed to carry back.
Most taxpayers no longer have the option to carryback a net operating loss (NOL). For most taxpayers, NOLs arising in tax years ending after 2017 can only be carried forward. The 2-year carryback rule in effect before 2018, generally, does not apply to NOLs arising in tax years ending after December 31, 2017.
If you had an NOL in 2018, you would have had no option but to carry it forward. The program would have calculated it and done it for you.
If you did not do your taxes in TurboTax, search for NOL and then click "jump to NOL" and you will see the screen below.
