This is a very easy and user-friendly tool, I've been using Turbo Tax since 2020 when my Accountant wouldn't let the public file in person in his office for fear of catching COVID.
Include Guam in E filing. It is part of the U.S.A I have always used Turbo Tax while I lived in California and loved it but as soon as I moved back home (GUAM aka U.S territory) they cannot E File for me and still consider it under foreign territory. I paid for their services but still have to mail in my tax return. :(
