This includes the full cost of
transportation (eg. airplanes, bus, train, rental car) and hotel accommodations,
less any reimbursements. It also includes 50% of meals and entertainment, if
not already claimed on the Meals and Entertainment screen. Expenses that fall
under the 50% rule are meals and entertainment where you have a receipt or bill
that identifies their cost separately.
If you attended a convention,
don't include those expenses as “travel”. They should be entered under
"Other Expenses", which is coming up. Expenses regarding your own
motor vehicle should go on the motor vehicle expenses page.
