Am retired military drawing retirement, disability&SS. Did some W-2 work in U.S. & 5.5 months 1099-Misc work in Canada. How do I treat this income? Do not own a business.

1099-MISC includes hourly, per diem, M/IE, gas reembursement, items purchased for the project.  Do I just owe tax on hourly income and delete all per diem, M/IE, gas, etc from the total non-employment compensation?
