Missing R56D coded SMD inductor where can I find one

Hi folks

I didn't know where to post it, but I thought I'd post it here. We tried to tidy up a friend's Mac Mini 2011.

However, it was given to the service before and the service stated that it would no longer be repaired and that the motherboard had to be changed.

When I took the device and opened it the R56D coded SMD inductor on the motherboard is missing.

If the service dismantled it, why did they remove it? Is a separate mystery...

My question is, where can I find this part? Even if I find a spare motherboard, I find it unnecessary to spend just for this part.

Thank you very much to everyone in advance.
