but it was under $600.
That doesn't negate your requirement to report it. The $600 limit is for the 1099. A 1099 is not required to be issued for amounts under $600. But that doesn't mean one can't be issued. Even if not issued, you'd still be required to report it, even if the gain was only $1.(Assuming you have other sources of income that makes your total income exceed your standard deduction)
