Give your reasoning why it is not connected to TP29, besides the fact your SQ5 pad is missing and that you can not see a trace connecting them.
There is quite a bit more going on with that board than what you can see. It's a 6 layer PCB, so there are 2 more PCBs worth of traces you can't see inside there that are connecting all kinds of things together, including connecting SQ5 to U5p8, TP120 and yes, to TP29.
