Amend tax return due to missing 1099 for RSU vesting

Hello members,

 

In 2018 I have RSU vested, and some of RSU were sold to cover the tax. The RSU tax information was on the W2 which was reported. However, in tax return, I forgot to provide the 1099B from my broker(I did not sell any of the share). In this case, since the tax information was already on W2, do still I need to amend the 2018 tax return with this 1099?
