Do I have to add a W-2 less than $500?

Yes. You are required to include all income on your tax return. If you have already submitted your tax return to the IRS, then you'll need to file an amendment. You can prepare this amendment using Turbo Tax, but you'll need to paper file the return. You should wait to mail the return until the original one has been finalized.

Please view the Turbo Tax FAQ for directions on how to file an amended tax return.
