Care Economy Payment

As a live-in provider, I received the Care Economy Payment of $500 as a check for $494.50 and a W2 that is zero on all boxes except line 14 (CA-SDI) in the amount of $5.50.   How do I go about filing my federal and state taxes?  Helpful if response could be detailed.  For example, I'm uncertain if I file $494.50 or $500, if it should be reported under "other income" or if could be added to line 1 of W2.
