a seller on ebay sold me this board, and now he claims that the board was intact, now where do I have to solder to restore the connection?

Not SO, SQ.

SQ2 is just ground, so pick any other ground spot for that one.

SQ5 you can use TP29 or TP120.

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. ;)
