After you've enrolled in benefits, here's how you can review what you've elected:
Benefit elections can be reviewed by navigating to the Myself tab, then looking under the Benefits drop down menu. One of the first items on the list will be "Benefits."
If you select that option, you'll be taken to your Benefit Summary page. This is where you'll be able to view which benefits you've opted into / out of and what the monthly cost looks like as well. Anything that has a red 'X' under the Status column is something you are currently enrolled in.
This page also contains start & end dates for those elections as well as plan documents. It is also where you'll be able to process Qualifying Events if necessary.
