Can't Delete BootCamp Partition

I’m having trouble deleting a partition from my internal hard drive. I’m using a late 2013 13” MBP running MacOS 10.14.6.

I created a 200GB partition on my hard disk as a student to run Windows 10 using BootCamp, and no longer have a need for it. After searching for how to delete it online, I opened Boot Camp Assistant and selected the “Install or Remove Windows 10 or Later Version” option and followed the steps. Next, I opened Disk Utility to verify that the process worked. I am no longer able to see the Windows 10 partition in Disk Utility, but it seems my hard disk is still partitioned. My hard disk should show a total of 500 GB of storage, but it is still only showing 300GB. As mentioned, I’m not able to see the 200GB Windows 10 partition anywhere in the Disk Utility.

I have run Disk Utility’s first aid function in recovery mode and no issues were detected.

Anybody experience a similar issue or have any insight on how to reclaim the extra storage from this “deleted” partition?

MacBook Pro 13", macOS 10.14

Can you check the output of

diskutil list

If you have missing disk space, retry the resizeContainer command that I have posted.

Are the warnings in the output anything to worry about?

Yes.

Reboot and hold Command+S, which will put you in Single-User Mode. In the black-and-white console, at the '#' prompt, run

fsck_apfs -s -o -y /dev/rdisk1

and post the output.

Thanks for your response! Output:

Looks like "EFI" might be the disk in question.
