Just as a general tip for future reference, you can get better definitions of these structures in WinDbg. In this case, for example, `dt ntdll!_TEB64` gives a fairly comprehensive definition of `_TEB64`. The offset of `TlsSlots` matches up with what you have here too, which at least shows it's correct.

Interesting, according to WinDbg's definition of `_TEB64`, the TEB has this field:
+0x180c WowTebOffset : Int4B
Not sure what the difference is between this and `wow64teb.Reserved1` (if there is one at all), but maybe we'll need this in the future (or maybe it's not what it sounds like)
