You will need to enter it manually. If you also have a loss carryover, they will be combined for a maximum 2018 loss of $3,000 on your joint return.
If you transferred last year's
TurboTax return over, you don't have to do a thing – we've already entered it
for you.
Otherwise, just open your
TurboTax return, search for capital loss carryover,
and then click the "Jump to" link in the search results.
We'll take you to the screen
where you can enter that info from your prior year return.
