I have more taxes to file but i can't find anywhere where to do that

What do you mean by "more taxes?"  Do you mean you need to add information to your own tax return?  Or do you mean you need to prepare another tax return for someone else--like a family member?

Do you have more than one W-2? Some taxpayers believe that they have to file each W-2 separately.

On the contrary, you add all your W-2s into your one and only 1040 tax return. If you "filed one W-2" and need to "file another one", please come back and tell us, and we will guide you through what you need to do.
