YOu're a smart Newbie!!!
Missus Fear ... ITA ... the best way to correct this is to unsew and cut new setting triangles. I usually oversize them. and once sewn in place, I press the whole top well, and then trim the excess. That way you can get it all nicely squared and trimmed before you add the borders/bindings.
You've got a lovely piece and you'll be more than happy you took the time to back track and correct it.
(and I bet you'll remember this and will never cut setting triangles wrong again!!
