Do I lose a capital loss carryover if I take the standard deduction for tax year 2018 ?

[Hal_Al]

Simple answer: No. 

But taxes aren't simple. You are allowed to use  either your standard or itemized deductions to reduce your taxable income before having to use your capital loss. So, in a year that you use the standard deduction, it;s possible that you might not have as big a carry forward, to the next year, as you would have had with a large amount of itemized deductions.

  TurboTax can handle it and will prepare a "Capital loss carry forward worksheet" to show the how much of your capital loss that will be carried forward to 2019.
