See this previous TT answer for important instructions on filing a Guam tax return:
Do i have to file state taxes if my slr is guam (intuit.com)
You can file your Guam tax return online here (note that you must register for an account if you don't have one currently): https://www.myguamtax.com/login.jsp
HOR and SLR are usually the same for most servicemembers, but there are technical differences which are well-explained here:

If you are active duty military, you file state taxes in your SLR.
If you use TT to prepare (but not file) your Guam tax return, choose "Foreign or US possession" as your state of residence. It is at the bottom of the state of residence drop-down list in the My Info section.
