Thank you so much! Adding "node" to the value of a variable works.

RefTeX provides a variable for this purpose:
,----[ C-h v reftex-label-ignored-macros-and-environments RET ]
| reftex-label-ignored-macros-and-environments is a variable defined in ‘reftex-vars.el’.
| Its value is nil
|
| Documentation:
| List of macros and environments to be ignored when searching for labels.
| The purpose is to ignore environments and macros that use keyval
| style label=foo arguments, but the label has a different meaning
| than a \label{foo}. Standard \label{...} definitions are never
| ignored.
|
| E.g., TikZ defines several macros/environments where [label=foo]
| defines the label to be printed at some node or edge, but it’s
| not a label used for referencing.
|
| Note that this feature is only supported if you are using AUCTeX
| and the functions ‘TeX-current-macro’ and
| ‘LaTeX-current-environment’ are bound. Also note that this
| feature might slow down the reftex parsing process for large TeX
| files.
|
| You can customize this variable.
|
| This variable was introduced, or its default value was changed, in
| version 24.4 of Emacs.
`----
You can customize this variable and add "node" if you want to ignore the
macro or "tikzpicture" for the entire environment.
