The OCC has provided infomemos on this topic:

I'd encourage you to read it thoroughly but don't blame you for not having found it. You will not be able to sell your puts. Under "Option Exercise" it states that you must provide an exercise declaration (EED) as automatic exercise is disabled for even deep ITM options. Under the "put option exercise considerations" section you will see that the OCC has not imposed exercise restrictions but your broker firm may also be affected by regulations that disallow you from taking delivery so you would have to ask your broker. Unfortunately since you don't state your broker I can't help further but the OCC documentation says:
"Questions about such rules or their applicability to the exercise of a given option position should be addressed to the brokerage firm holding the investor’s position."
and they are the final word on options traded in the US!
My professional guess is that most brokers will cash settle ITM options but may have differing views on the fair value of the underlying so I can't tell you what that value will be in your case.
