You should have actually posted this question in the Tech Support section, but using 20GB of data in five days is quite easy, depending on what your devices are doing and what definition you're streaming in. Streaming in HD can use around 3GB per hour, so two average movies would be around 12GB. Streaming in SD uses aroung 700-750MB per hour.
It's best to stream in the lowest definition that looks good to you, which, for most, is SD. The Video Data Saver, which is on by default in Gen5, should, when streaming, throttle your speed to such that a streaming service that automatically detects the speed and can adjust the definition accordingly will switch to SD. You can turn the Video Data Saver off, or pause it for four hours, to stream in HD if you wish, but, again, that can use a LOT of data. You can turn the Video Data Saver off, or pause it, through the Hughesnet Usage Meter or by signing in to the Hughesnet myAccount site ( http://my.hughesnet.com/myaccount ) and going to the Settings tab. But, with that said, as shown, if you want to save data while streaming it's best to leave the Video Data Saver on.
But, again, depending on what your devices are doing it's entirely possible to use that much in five days. At the higher speeds some get with Gen5 it's possible to use 20GB in a little over an hour if something is downloading full out.
Glasswire is good for Windows based computers, as it can tell you not only what data is being used by the computer it's installed on, but also what on that computer is using the data, and how much each program/app/process is using. Set options (to the upper right of the circle graph in the Usage tab) to "Incoming & Outgoing" and "External". Glasswire is free. https://www.glasswire.com/
If you have a satellite TV receiver (like a DirecTV Genie or a Dish Network Hopper) connected to HughesNet that can use a lot of data, as well, even when you are not streaming, and even when it's "off", as it's not really off, but in standby.
In Windows 10, unless you have a need for it, it's best to turn off syncing, disable or uninstall OneDrive, and, unless you have multiple, networked PCs, it's best to turn off "Updates from more than one place", as if it's on, you could be sharing your downloaded updates with people on the internet (getting their updates from your computer instead of Microsoft's servers).
