My online field portal has disappeared, how do I get it back? When I login my only portal is the accounting one.

When I went signed in online before I could choose between the field portal or the accounting portal. I only have the accounting portal now. I don't know if I did something to make it disappear. I have been trying to migrate my desktop accounting to online so maybe something happened. I am waiting for a call back with an issue I was having with that so maybe it can all be fixed at the same time.
