How do I know if I made money in another state?

I did some part-time consulting. I was living in Georgia. The company is based in California. I was working remotely. Is this considered "making money in California"? I have a 1099. The company address is California, but my address is listed in Georgia.

You r consulting income is Georgia income.  In general, a state can only tax a nonresident on income with a state source.  For wages, income is earned/state source in the state you physically did the work in.  The location of the company is only relevant if you worked in the same state.
