E&O insurance covers international tax penalty?

I from time to time have some clients with international relevance. Though this is not my main business, I do not want to face high risks with the harsh penalty related to international tax forms.
The E&O insurance I bought does not list international tax preparation or similar items but just list tax preparation as one covered area. Is that sufficient? Should I ask them to specifically list international tax as one covered area?
Thanks.

Probably best to ask, and get their answer in writing, just in case.
They likely have additional engagement letters they would want you to use to try and limit their liability.

The the US forms, such as 8938, "international"?

I certainly hope it is covered. I feel like these cause our biggest risks.
