Audio+ v2 GPIO 19

Got a Audio+ V2 since some time on a pi zero W 1.1.
I would like to wire a MEMS mic on it. I need to use GPIO 19 (PCM_FS) . The hole labeled 19 on the Audio+ board is linked with GPIO 26 of pizero, is it an error?

I can not find any other place to solder to get GPIO 19


Yes you found a labeling mistake,
GPIO19 is LRCK for i2S there is no exposed pin hole

but with some soldering you can find it here on the pins header:
