I have filled my 2018 tax return but CPA did not consider my Stock capital loss in crypto currency, can i get use my capital loss from 2018 in tax filing of 2020 ?

you should have the CPA prepare an amended return if he knew about the crypto but failed to report it.  if it can be used in 2018 it must be but the amount that's used would depend on how much was actually used to reduce your 2018 taxable income. then the unused loss, if any, would be carried to the 2019 return.  we can't see your returns so can't tell you what the capital loss to 2019, if any, would be.

Q. Can I just wait and  use my capital loss from 2018 in tax filing of 2020 ?

A. No. The 2018 capital loss must first be applied to the 2018 tax return.  It that results in any carry over, the carry over must next be applied to the 2019 tax return.  Only if that results in further carry over, can it be carried to 2020. And then only the amounts resulting form the previous year calculations.
