Not exactly following the years.....but do you have any current 2019 gains? You get to first offset the loss against any gains you have each year so that can use more of it up. Then after applying the loss to the current gains you can take a max loss of 3,000 (1,500 MFS)per year. Turbo Tax does all the calculations for you. Just enter the prior year carryover amount.
I'm not sure you have to enter the minus sign. I'll have to check that out. Also I would be surprised if transferring from 2018 pdf would pick that amount up. PDF only transfers basic items like name & address.
To not reduce the carryover loss is based on your taxable income not your tax liability. Look at 2018 line 10.
