House-Hack Verification?

Hello BiggerPockets community!

This may be a very simple question but I was wondering if anyone here knew what sort of documents do I need to prove that I lived in the property for the 2 out of 5 years owned in order to get the $250,000 tax free. If there is any other documentation or proof that I would need for this process I'd love to hear more about it as well.

My current situation is that I have a property that I purchased for $150k that I'll be selling for $240k this month. I am debating if I should go forward with a 1031 which has the obvious time deadlines, or just to get the up to $250k tax free. I have owned the property a little over 5 years and I have lived in it for at least 2 so no problems there.

Thanks in advance as always!
