I was skeptical of this, but it checks out: I easily got ChatGPT to print out the full text to The Tell-Tale Heart, without any errors at all in the various spots I accuracy-checked.

Granted I chose it because it's a very short public domain work - I was more skeptical of its technical ability to recall the exact text without errors than of the ability to trick it into violating copyright law.

I still suspect it's much easier to (accidentally) trick it into writing a fanfiction of a copyrighted work that it claims is the original than it is to get it to produce the true original, though.
