My wireless 4K box is now behind my TV and for the life of me I can’t locate the IR receiver on it to use my IR repeater. I can’t find any specs online. Any suggestions?
Specs for the various set top boxes are here:

Sadly they don't indicate where the IR receiver is.
It may have multiple IR sensors because it still gets the signal with the entire front covered. Just place the repeater anywhere near the front but not directly on it to get a wider beam.
