Capital Loss Carryover - When Capital Gain is under 0% TI threshold

I have a capital loss carryover, but this year I have a capital gain that is under the 0% threshold.  My preference would be to save my CLC for a future year,  and not apply it to this year's gain.   TT is not letting me do this. 

Does IRS require that the CLC is applied to any capital gains, regardless of amount and taxability?
