First I’d try to sell them tomorrow for a penny, even if they are normally quoted in nickels (not sure about these), since you might get lucky and catch a bid.
Alternatively, if you set up some put spread for another put contract you want instead, you may well be able to unload them by taking a kinda bad price on the other leg in combination, which depending on the terms, would be the next best choice. I guess then close the other leg, like you said, if you don’t want new puts.
Failing these, you can do the “Dollar For Lot” paperwork at IB and try to give them the whole position for $1. I’m not sure if this works for options, but it’s worth a shot.
Don’t delay, they may be busy and if the ticket goes thru after EOY, that doesn’t help your taxes.
