Reapplying after a rejection

[Veev]

I applied for a US visa in 2015 but my application was rejected.
I am currently reapplying but there i noticed there is no field to input what countries i have visited after the rejection.
Is this okay?
How would the officers know what countries i have visited after then?

that information would be available on your passport, computers, and if they need more information, they will ask.
