grammar - where should the adverb 'yet' be put in the sentence?

I am always not sure where to put the adverb 'yet' in a sentence.
In my example below, for me, both versions seem to be correct but if anyone could
double check that would be great.

I was wondering if you have heard anything back from ... regarding my ... yet?

Or

I was wondering if you have yet heard anything back from ... regarding my ... ?

Best wishes!
