Cannot manipulate my files in Ubuntu 18.04

I am having major problems with my data partition which I have mounted at /home/data. Any time I try to download a file to any location within this folder I get a download failed error (with both Chrome and Firefox). If I try to delete files using the File Explorer, it will show them as getting deleted (the files will disappear from the folder) but when I leave and re-enter the folder the files are still there.

In the beginning I was getting errors that files were 'Read-only'. So I tried to remount the partition using

sudo mount -o remount,rw /partition/identifier /mount/point

This seemed to solve the read-only issue, but it didn't fix the downloading/deleting/moving files issues. When I run ls -la from the /home folder, it shows

drwxr-xr-x  5 root  root   4096 Jan 10 16:45 .
drwxr-xr-x 26 root  root   4096 Apr 16 13:01 ..
drwxrwxrwx  1 root  root   8192 Apr 26 23:16 data
drwx------  2 root  root  16384 Jan  9 19:42 lost+found
drwxr-xr-x 34 steve steve 4096 Apr 29 14:50 steve

Which leads me to believe that I still don't have ownership over the folder, so I tried to get ownership using sudo chown steve:steve -vR data/ which gave me the following output for each file located in data

changed ownership of 'data/' from root:root to steve:steve

But the problem persists and the output of ls -la remains as:

total 36
drwxr-xr-x  5 root  root   4096 Jan 10 16:45 .
drwxr-xr-x 26 root  root   4096 Apr 16 13:01 ..
drwxrwxrwx  1 root  root   8192 Apr 26 23:16 data
drwx------  2 root  root  16384 Jan  9 19:42 lost+found
drwxr-xr-x 34 steve steve  4096 Apr 29 14:50 steve

I also tried chmod 777 ./data but this also hasn't helped. At this point I don't know what else to do.

Some extra info, I am using Ubuntu 18.04 on a dual boot with Windows. The computer was fine this morning but in the afternoon sometime is when it broke down, but I don't remember doing anything out of the ordinary.

After trying to remount the partition in the recommended location from the comments I came across a new set of errors which led me to the eventual solution.

I had to run this series of commands

sudo ntfsfix /dev/sda1
sudo umount /dev/sda1
sudo mount -o rw /dev/sda1 /home/data

Now I have full r+w access again. The key here was the sudo ntfsfix /dev/sda1 command, as I guess the problem came from a windows restart or hibernation file that was present in the partition, and this command fixed that for me.
