Macintosh HD not using entire drive

I have a 2016 15" macbook pro with a 256gb ssd. Only 122gb are used by MacOS. How do I get MacOS to use the entire drive? I believe this happened because of a botched bootcamp uninstall. Disk utility shows the following:

Here's the output from diskutil list

/dev/disk0 (internal):
   #:                       TYPE NAME                    SIZE       IDENTIFIER

Thanks!

I just needed to resize the container (because apparently that's a simple thing to do). I first had to restart into recovery mode and run firstaid on the container. I ran it on all 3 of the drive, the container, and the volume to be safe, but I'm certain only the run on the container did anything. Then I restarted and logged in and in a terminal ran the following:

diskutil apfs resizeContainer /dev/disk1 0
