How do I submit a royalty report, and when is it required?

I would like to know how to file a royalty report, e.g. tracking my income, which is required per the EULA. I made $200 (minus fees) last quarter from a go fund me for my Planetary Settlers game I am developing. Only $5 of that was the purchase price for the game (one donor). Am I correct that I don’t have to file a report because this falls (well) below the $3000 limit?
