I have Xfinity, a Netgear CM700 modem and Orbi mesh router for my home.   There are two of us.  We stream TV via netflix and ATT Watch and I have set picture size to 1080p Standard Def, the only other thing we do is  email and normal internet.  We are not gamers.  For the last two months I have gone over 1 Terabyte and can't figure out where the data is being sucked up.  Does anyone have any ideas if it could be through this modem/router and how to check?

1080p and standard definition are 2 different sizes. If you're streaming 1080p video, you're using 2-3gb per hour of usage per device. That averages out to 333 hours of streaming a month or 11 hours a day (30 days)

Again thats per device. If you're watching on 2 tvs cut your rates in half. Plus if you're watching videos on phones/tablets/etc. 

Netgear does have traffic monitoring but not by device unfortunately. So you're kind of to the point of having to test things to find out whats using the most data. 

You could use the netgear traffic monitoring or xfinity's own data usage monitor. Stop streaming on the tv's for a day or 2 and see how your data changes. If it decreases, then you know its from the streaming. If it doesn't decrease, then go through your attached devices list and selectively disconnect each device and see how your data changes. 

If you're on windows 10, you can check on those devices under your network status how much data you've used the the last 30 days. Android also has a data monitor built into their phones. Not sure about iOS as I'm not a mac guy.
