Not sure where to go from here. I'm still relatively new to suduko so are there any techniques I could use here?

You can remove 4'5'8 from the far right cells in the middle box. With the 3 and 6 solved. You know that those four cells (2, 4, 5, and 8) only contain that, so the other ones (the 3 cells in the right) cannot.
Also, the top line from the bottom group.. the 4,5,8 trio is there too. That will clear out those numbers from any cells that may also have 4,5,8 on that line.
Thank you so much! I don't quite understand this so I'm going to have a look in the morning and try wrap my head around it
It's cause those are the only locations in that row that 179 are in, so the 458 can't be there.
