The IRS gets the correct address when the trust files its own tax return (Form 1041) and the K-1 you enter on your individual income tax return does not get transmitted to the IRS.
You do have the option of entering a foreign address for both the trust and a partner - you just have to "check if this is a foreign country. Guam is included as an option for "Country".
See the attached screenshot for an example:

The screenshot is from TurboTax Business while @dpaulino21's post was from a personal version of TurboTax, which does not have that option when entering a K-1 that was received (see screenshots below).
