Is there a name for an answer to a question that does nothing but rephrase the question in an answer form? For example, if you were asked something that you didn't know the answer to and were trying to be funny / intentionally not helpful.

Examples:

A: It's a house for dogs.
Q: What is the typeDefinitionAccessCode variable used for?
A: It's used to store the access code of the type definition.

I think you might be looking for tautology:

[Tautology] is an argument that utilizes circular reasoning, which means that the conclusion is also its own premise. Typically the premise is simply restated in the conclusion, without adding additional information or clarification.
