@Cynthiad66, yes, understood. tagteam said that in an earlier post, but NY apparently still has that deduction as explained by @ToddL99 so I am entering it in the Federal questionnaire and it appears to get passed on to the NY forms.
Actually, every answer here is partly wrong, because the experts all missed that one of your accounts was a 401(k).
With a 401(k), you only pay tax on the money that is withdrawn, when you retire or otherwise. Nothing that happens in the account means anything until you withdraw the money—you don't report gains, you can't deduct losses, and you can't deduct investment fees, before or after the 2018 tax reform. Your tax "deduction" is the fact that if there is less money in the account, you will pay less income tax when you withdraw it.
For your regular broker account (not a 401(k), not an IRA, not some other kind of tax-advantaged account) the answers are correct.
