Hi Courtney
No worries. I’m here to help.
16SGC and 17SKT overlap partially - maybe 50% - with the eastern half of 16SGC covering a similar area to the western half of 17SKT. So, if your AOI was in that area, then you have more data to play with 
Here’s the overlay of the UTM Zone grid that shows your Tiles relative to UTM Zones 16 and 17
I hope this helps.
Cheers
Jan
