1. I'm not familiar with the reporting of options trading. I was referring to changes to the carryover of short- and long-term capital losses and any other carryovers that might affect your 2018 tax return.
2. Amending 2017 using TurboTax you would first have to recreate in 2017 TurboTax your originally filed tax return, then perform the amendment. Given that you mentioned options trading, it's likely that recreating your originally filed 2017 tax return with 2017 TurboTax would be an onerous task.
